Many links seem to be broken

[AneesHl]

Many hyperlinks seem to be broken, e.g. on this page the second paragraph contains the words --fast target property links to https://www.lf-lang.org/docs/#fast which doesn't exist.

FYI, when building the website locally using yarn build I get the following output:

yarn run v1.22.21

[WARNING] Docusaurus found broken anchors!

Please check the pages of your site in the list below, and make sure you don't reference any anchor that does not exist.
Note: it's possible to ignore broken anchors with the 'onBrokenAnchors' Docusaurus configuration, and let the build pass.

Hm, I thought we configured Docusaurus to treat broken links as a failure, not a warning. Perhaps @axmmisaka could comment on this?

[axmmisaka]

There's another option for broken "anchor" which is different from broken "link".
Over time the documentation becomes a mess and some deleted sections were still referenced.
Some others were caused by malformed markdown file, e.g. arduino.mdx: misuse of h1 in md (# in lieu of ##) and ## Command-Line Arguments - same.

I have made a branch https://github.com/lf-lang/lf-lang.github.io/tree/fix-broken-links where I enabled the option to fail the build should any anchor be broken; yet I do not wish to fix them 1 by 1, so I would see if anyone else would be interested in fixing these links with their best judgement......
