…er tool (#1692)" (#2900)

This reverts commit f470f40.

This configuration entry was previously required in order to work around a bug in the "markdown-link-check" tool that
resulted in false positives for links to anchors created by HTML anchor tags.

The bug in the "markdown-link-check" tool has since been fixed, and this project updated to use the version of the tool
with that fix. So this configuration entry is no longer required.

The now superfluous configuration entry is hereby removed in order to ensure more comprehensive link check coverage.

Previously, this reference to Arduino CLI's `directories.downloads` configuration key misspelled the name as
"directories.download".

The project includes a documentation website which is generated by the MkDocs static site generator. The site contains a
navigation panel which lists the available documentation pages.

Rather than being automatically generated from the contents of the `docs` folder, the contents of the navigation panel
have been explicitly defined via the MkDocs configuration file. This means that the project contributors must remember
to update the configuration file when development work results in the addition or removal of web pages.

This was not done when the `config get` and `debug check` commands were added. The web pages are generated as expected,
but the missing configuration file entries means that a visitor to the website would never know of their existence, and
could only access them by hacking the URL.

The missing entries are hereby added to the MkDocs configuration file.

…cations (#2902)

Arduino CLI restricts which characters can be used by platform developers in their vendor, architecture, board, custom
board menu, and custom board option identifiers.

Previously, the information was only documented(?) in the "FAQ". This type of requirement must be present in the formal
specifications. A platform developer is unlikely to ever think to look for such information in the FAQ.

In addition, the inclusion of such information in the FAQ is not appropriate as this is intended for end users of the
Arduino CLI application and end users have no control over which characters were used by the platform developers in
their identifiers. So the presence of the information in the FAQ only harms readability by introducing unnecessary
complexity into a subject that users often struggle to understand.

…ath` configuration key (#2919)

The "Configuration" documentation page includes information on the default values of the configuration keys.

The default value of the build_cache.path configuration key was recently changed, but the documentation was not updated
accordingly.

The documentation is hereby updated to provide the correct information regarding the default value of the
build_cache.path configuration key.

Previously, the information was provided in the list of keys. That is a non-standard location for the information as
there is an established convention of instead providing this information in the separate section of the page dedicated
to documenting default paths. In addition. the location in the keys list became more problematic for the new default
since it is operating system-specific and thus the increased volume of documentation content would be awkward to fit
into the nested list of keys. For these reasons, the documentation content was moved to the standardized location under
the "Default directories" section of the page.
