A11y improvment (part 1)

[basile-parent]

First part of the improvments proposed in #544 :

• removing the "radio" attribute on buttons when it's not relevant
• properly grouping the relevant radio button

The only thing I could not do is to translate the new locale entry to all languages

Thank you for the PR.

The project has prettier configured, but for some reason, your PR uses a different formatting which results in a massive change - this makes it very hard for me to review it; the build won't pass as well.

Can you fix the formatting? I don't think that the change you mean to introduce should change 300+lines.

[basile-parent]

Yeah, I don't know why it don't apply... I'll fix that and push a new commit

@petyosi I think we are good now

The current state of the PR has typescript failing and hooks with missing dependencies. Also, it changes the spacing of the toolbar, making it wider:

The missing imports were so weird... It should have worked at all 🤔 Anyway, it's fixed.

I also fixed the spacing but had to make some compromises to have the exact same render : I had to externalize the <div className={styles.toolbarGroupOfGroups}>. If not, there are additional margins on the sup/sub formatting (only difference).
If you think this difference is acceptable, I can rollback this change.
