v4: Improve accessible name of version dropdown in docs navbar (#36504)

- add `sr-only` "Bootstrap", which will be part of the accessible name
- extra `sr-only` text to give some context - that the dropdown is about switching versions
- remove the redundant id/aria-labelledby for the dropdown
- change the control from `<a>` to `<button>`
