Add filetypes and improve web categorization

[benelan]

Summary

Thanks for putting this together! I made some additions and changes that other may find useful, so I'm opening this PR. It covers a bit of ground so I can open separate PRs if you'd prefer. Let me know if you'd like me to provide docs/sources for any of the new filetypes.

• Add additional common documentation files
• Add a variety of filetypes I use as a web developer
• Create new web-related categorizes and labels
• Recategorize ts to Typescript. I can switch this one back if the video filetype is common, but I had never seen it and Typescript is a household name for web developers
• Add the wezterm TERM
• Add tmux-256color TERM
