[Form] Remove `:end-before:`, `:start-after:` as it's not used anymore

Fixes #16466 (I deleted the branch of my old pr accidentally, so I recreate a new PR)

1. The `:end-before:`, `:start-after:` directives is not supported by the new ReST parser, so it is displayed in the page:
2. As you can see on this page, the 2 options are duplicated in several places in the documentation ([here](https://symfony.com/doc/4.4/reference/forms/types/date.html#choice-translation-domain) and [here](https://symfony.com/doc/4.4/reference/forms/types/choice.html#choice-translation-domain)) whereas it is not necessary.

**Reviews are welcome! :)**
