[docs] Remove "-" in heat-map and tree-map urls

[alexfauquette]

Since we plan to call those components Heatmap and Treemap having a "-" in the url makes no sense. So I propose to fix h=this before releasing one of those components

Maybe we should update:

mui-x/docs/scripts/reportBrokenLinks.js

Line 48 in d7abca3

const usedLinks = { ...usedLinksCore, ...usedLinksX };

to be:

 const usedLinks = usedLinksX; 

I'm not sure that checking links across Base UI, Material UI, and Joy UI repositories in the future will scale well (e.g. this PR whose build is failing because we need mui/material-ui#42697). But it's indeed nice that this works today.

The impact on other PR is more my fault than the script.

You can bypass the test by running it locally and saving the updated file.

About this specific PR: I merged a PR with the test broken because I remembered I can bypass it, but obviously it was not the correct way to do it

About linking to base, joy, material, and the blog. The main reason was the rewording effort of Sam. Because titles impact the anchor link, and so our link anchor to the core got broken frequently

Fair enough, this works as well.

I see, even ahrefs doesn't report them. Don't hesitate to upvote https://ahrefs.canny.io/site-audit/p/find-broken-html-anchor-link 😁
