fix: make site health check easier to use

chore: add main README.md file to project

More work towards closing coder/internal#532

## Changes made
- Added Bash script to run `terraform validate` on all relevant repos
- Updated `package.json` and CI to use the script

## Changes made
- Added `CONTRIBUTING.md` file (mostly copied over from modules repo, with some parts reworded, and some sections added)

## Notes
- This definitely isn't the final version of the file (it should definitely change we have more Bash stuff added), but it felt like it's in a good enough spot for an initial release

## Changes made
- Added back CI steps for validating the codebase for typos and formatting
- Updated README validation CI step to be dependent on typo-checking step
- Updated configuration files as needed to support the new CI step
- Updated all files that were previously getting skipped over from improperly-set-up CI logic

## Changes made
- Added functionality to validate the structure of module README files (frontmatter and the README body)

- Updated README files that were previously violating README requirements (the old modules validation logic wasn't catching these)
- Changed `ValidationPhase` from an int to a string

…typos-1.32.0

## Changes made
- Copied over all changes to existing modules, making sure to preserve
all relative path updates made specifically for the Registry repo
- Copied over all modules that were created since the last sync
(Windsurf, Devcontainers-CLI)
- Copied over changes from the `test.ts` file

## Notes
- This PR does not cover coder/modules#426,
which contains a few changes around updating the Bash scripts and the
contributing README file. @f0ssel tagging you so that you're aware, but
I'll be taking care of the `CONTRIBUTING.md` file

## Changes made
- Fleshed out main top-level README file
- Added formal docs for code of conduct and security (that just lead to
the Coder Docs)
- Revamped contributing guide
- Added a few images to help support the new docs

## Notes
- Just because we're not supporting templates for the moment, I did
deliberately limit the number of mentions to it.
