Henrik Lissner a70e634ebd refactor(:lang): move tree-sitter init 
Moved add-hook calls (for tree-sitter initialization) into their
respective modes' config blocks, or nearby, to be consistent with how
other, similar tools (like lsp!) are initialized, and does so at
runtime, rather than at expansion/compile time, which eval-when! caused.
