Thomas, thanks for this contribution. However, we had to revert most of the changes for some reasons:

• In Symfony Docs we don't use the "we" form ... so this text can't be included -> "Now we need some [...]"
• I didn't agree with the removal of the last phrase because it's important to note that we're using jQuery but we're not including it, so you must do something not explained here to be sure that jQuery is available.

We kept the button -> link fix and the new jQuery link is nice too. Thanks to your contribution, we realized that we need to give some clue about how to include jQuery in case the reader is lost. So, the new paragraph contents are as follows:

The goal of this section will be to use JavaScript to read this attribute
and dynamically add new tag forms when the user clicks the "Add a tag" link.
This example uses `jQuery`_ and assumes you have it included somewhere on your
page (e.g. using Symfony's :doc:`Webpack Encore </frontend>`).

Thanks as always for understanding 🙏
