Firefox Developer Tools docs is removed from mdn/content

[yin1999]

What is the problem?

Firefox Developer Tools docs in en-US is now redirected to Firefox DevTools User Docs by mdn/content#14140

Should we follow this changes in this repo?

[SphinxKnight]

Thanks for the heads up @yin1999, I guess the workflow for this would be to use yarn content --delete redirect for every current page under tools

[SphinxKnight]

After fixing a missing logic w/ mdn/yari#5814, I believe using the command line with
yarn content delete <slug> <locale> --redirect https://firefox-source-docs.mozilla.org/<sthg>
will work.
For instance, to delete/redirect one of the French page, I'll use
yarn content delete Tools/3D_View fr --redirect https://firefox-source-docs.mozilla.org/devtools-user/3d_view/index.html

(quick reminder: yarn content works from /content directory whereas yarn tool works from /yari directory)

[SphinxKnight]

if it may be of any help to any maintainer out there, here is the script I used for the French "surface" of Tools: https://gist.github.com/SphinxKnight/16d971e073338c5da4403874a3d8227b
I hope this would help reduce the workload (leaving only the pages for Tools that you may have in addition to the ones French had)

[yin1999]

I have wrote two scripts(in go and python) to deal with removing Tools section.

It resolves the Tools section with the following steps:

• List all the file with .html and .md ext, save the path to a string list.
• sort those path with inverse lexicographical order
• get the redirect url by GET "https://developer.mozilla.org/en-US/docs/" + <slug>
• exec command yarn content delete <slug> <locale> --redirect <redirect url> -y at content repo dir (upgrade to @mdn/yari@0.9.60)

Some documents need to be resolved manually (then run the script below again). The script won't resolve the tools section in conflicting dir neither.

I have precompiled the executable files below (for go).

l10n-fr taken care of in #4841 by @SphinxKnight 🤗

[yin1999]

l10n-zh is resolved by #4844 and #4845.

[myshov]

I have a question. Does anybody know Is there a plan to add localization to https://firefox-source-docs.mozilla.org/devtools-user/index.htm? It seems that a good amount of translations will be lost.
