Since (annotation) - support multiple lines

[ShaneBeee]

Description

This PR aims to add multi line support for the "Since" annotation.
I noticed lately some "since" lines are getting a little long, and are somewhat unreadable.
This change can make lines easier to read and decipher which version added what.
This will help further down the road also when more and more changes are done to a syntax.

Example of ExprName:

Example after Change:

As part of this PR, I changed since in ExprName (so we have a nice little example)

Bonus:

Fixed an issue with the "new" tag not showing up in docs when version doesn't fully match doc version.
ex: Skript version is 2.10.0, doc version is 2.10 (these weren't matching)

i think i'm probably alone, but i find the current option more pleasing to read
I don't really have any objections to changing it, though.

Just to note, you can still do a big ol long string if you want. It does not auto-split them.
I just found some of them (like ExprName) were getting a smidge unruly, and possibly in the future may get even more unruly.
