Language additions and sorting filetypes

[felixnorden]

Wanted to add in some additional language comment types in here as I was lacking some of them myself in my flow using LazyVim! Please let me know if there's anything needed further to get this merged in!

This commit will:

• Add in comment support for:
  • sh files
  • zsh files
  • solidity files
  • c files
• Sort all languages in alphabetical order based on filetype/name
• Rename the config table inside the config to languages as written in the TODO above

Sounds like a good plan, I’ll look to get those pieces covered tomorrow with a new commit to make sure we have a non-breaking change and update docs!

@JoosepAlviste , I added in the changes but wasn't sure about how to mark the config field for deprecation properly. Apart from this, I think that the logic should be in order for merging languages and config based on the internal logic and allowing for overrides/extensions.

Let me know if you want me to put the merge from keep to force in the table merge, however, in case this needs to be done for end-user overrides/extensions to have priority over the supported languages out of the box!

Roger that, will have a look on your comments and make sure we cover that as well! 👍 thanks for taking the time to go through it!

Looks great now, thanks for the contribution! And thanks for taking care of the config key renaming 😄
