[PATCH 0/5] docs: more improvements to sendemail documentation

From: Aditya Garg <gargaditya08@live.com>

Hi all

This patch series adds more improvements to the sendemail documentation.

The first patch links the OpenSSL's `verify(1)` manual page to the documentation of `-CAfile` and `-CApath` options, mentioned in a very confusing way in the documentation. The changes are similar to what Junio suggested in https://lore.kernel.org/all/xmqqbjraf29c.fsf@gitster.g/

The second patch adds the `sendemail.outlookidfix` config option to the documentation, which corresponds to the `--outlook-id-fix` command line option. The documentation of the same was left by mistake before.

The third patch adds an OAuth2.0 credential helper link for AOL accounts to the documentation.

The fourth patch adds a paragraph explaining the `sendmailCmd` option of git send-email, and giving users an idea of how it can be used to support proprietary APIs like Proton Mail API.

The last patch adds a paragraph explaining the options available for Proton Mail, which has been increasing in popularity recently.

P.S. all the patches are being sent using `git-protonmail`, linked in the fourth and fifth patch!
