MDL-79003 js: Bump stylelint and components

Stylelint 15 deprecates a heap of rules which will be removed in 16.

We can't use 16 because it's ESM and requires a big restructure of our
build process.

We can temporarily silence the deprecations and then when we update our
build tooling we can make use of @stylistic/stylelint-plugin to add the
rules back.

This commit:
- bumps stylelint and related dependencies accordingly
- fixes issues identified with newer sniffs
- temporarily silences deprecation warnings
