### Description

<!-- Please explain what your PR is about:
     - reasoning for the change
     - some details of updated code
     - any noteworthy choices to be aware of
	Please refer to any related issues by #<issue_id> -->

Bumping MPL version - it turns out that Hist (which uses boost-histogram) depends on mplhep, which in turn requires matplotlib 3.4+. So I migrated the patches and bumped MPL.

I noticed micropip doesn't seem to respect extras, that is, `await micropip.install("hist[plot]")` doesn't seem to work. (will investigate later)

* Updated matplotlib to 3.5
    * Added fonttools
* Updated yt to 4
    * Added `cmyt` and `unyt`, which I am pretty sure are yt specific. At least by looking at the name. 😆 
    * Also `colorspacious`
    * Also `tdqm`
    * Also `tomli` and `tomli-w` (backported from the next yt release to avoid adding a dead dependency `toml`)

Closes #2088 too. Also 3.5 was the first version to officially support 3.10, I think.
chore: matplotlib 3.5.1, yt 4. <!-- Thank you for contributing to Pyodide! All improvements are welcome,
