fix(mason-tool-installer-nvim): Use mappings function for null-ls names

[krzysztofgb]

📑 Description

Replaces null_ls_to_package mappings table with mason-null-ls's provided getPackageFromNullLs function for mapping package names to Mason names.

ℹ Additional Information

• Link to mason-null-ls function used: here
  • This function uses the null_ls_to_package table under the hood while also fixing the names of package names following "normal" conventions
  • This function was introduced here and a lot of "normal" mappings (including clang_format -> clang-format) got removed from the mapping sources as a result
• This provides an alternative fix to the issue I was having in fix(java): rename clang_format to clang-format #837

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

@mehalter You're the expert on this stuff, more than me 😅 Can you take a look whenever you get time and see if this makes sense?
