A PR to work on upgrading ux.symfony.com AssetMapper 6.4. Development for 6.4 should slow be "feature complete" within a week, and we can finalize this. There is also some work to do still on StimulusBundle & AssetMapper 6.4.

TODO

* [X] Update install instructions on the homepage - done in #1254

Cheers!
