refactor: Replace react-bootstrap MenuItems with Antd Menu

[kgabryje]

SUMMARY

This PR is first of the series - the goal is to get rid of all react-bootstrap's MenuItem usages. In this PR I refactored CopyToClipboard, LanguagePicker, HeaderActionsDropdown and DateFilterControl. In the case of DateFilterControl, I also fixed styling bug (as on the screenshot below) and replaced Input component for UI consistency.

• Introduces new feature or API
• Removes existing feature or API

@rusackas @etr2460 Can you take a look?
I just noticed that I forgot about uppercasing in DateFilterControl... but do we actually want it? In my opinion it looks a bit nicer now (see the first and second screenshot).

Just a note that #11491 may affect this, or vice versa.

[kgabryje]

@rusackas I rebased it to use changes from #11491

[rusackas]

One remaining nit here about the 30px value we discussed on another PR, but in general this LGTM. Approving, but not yet merging in case you'd like to tackle that tweak here, or rebase if the other PR comes in first.
