Inline links cannot have non-special character in place of third end-character

[JulianGro]

Inline links cannot have non-special character in place of third end-character.
Apparently Sphinx will always interpret the third end-character, even if there is an "invalid" character there.
Meaning that a link like:

`English <https://docs.vircadia.dev/>`_man

won't work. In this case Sphinx will try to interpret m as part of the "end-string", fail to interpret it and thous fail to create the link when in the build.

To work around this problem, one either puts a special character in the place of the third end-character or a space behind the link, depending on if you are okay with having a space in the finished build there or not.
E.g.:

`English <https://docs.vircadia.dev/>`_\man

or

`English <https://docs.vircadia.dev/>`_ man

Interestingly a . seems to be a special case. I assume since people often want to put a . behind a link, they added this exception.

Keep in mind that _ has the function of anonymizing a link, so it should not be used to work around this limitation.

My understanding is that Sphinx should ideally just interpret every character it doesn't know like it does with ., but I will have to do some digging to see if this limitation can be fixed or not.
