Handle AUCTeX's new mode naming convention

[Rathur421]

Hi, thanks for maintaining this package, it's great!

To quote this other pull request :

Recently, AUCTeX renamed several of its major modes to avoid shadowing emacs built-in modes. This is documented here: https://git.savannah.gnu.org/cgit/auctex.git/tree/doc/changes.texi

As a result, if one has the newer version of AUCTeX (the version currently available from ELPA) then when they activate LaTeX-mode, lsp will be unavailable.

So I just added LaTeX-mode to the variable lsp-ltex-active-modes and it's working.

Also, I was wondering if we shouldn't add by default the other latex mode (i.e. TeX-mode, tex-mode and yatex-mode)

You are missing a - here.

Thanks for spotting this, I did the fix quickly on GitHub and didn't even consider it as a possible mistake

If those major modes work, we should add them by default.

Thanks!

Just to let you know, I've made a bit of digging and I didn't see any TeX-mode which are really used around.
The emacs manual says that it only provides major mode variant. As for yatex-mode it seems like it's a japanese package which is still being updated regularly (last update 7 months ago). So maybe it is worth adding it, but I'll let you choose.

Sorry for the late answer, and thanks again for maintaining this package !

Feel free to open PRs for these major modes! :)
