False positives with tags (i.e. non-tags are extracted as tags)

🐛 Describe the bug

obsidian.nvim is generating tags for things which are not tags. I first noticed it with certain URLs in my notes, e.g. the following text:

- The GHCi debugger: https://downloads.haskell.org/~ghc/9.4-latest/docs/users_guide/ghci.html#the-ghci-debugger

...results (incorrectly) in the tag #the-ghci-debugger in obsidian.nvim. (Obsidian doesn't treat this as a tag.)

I'm not sure Obsidian's exact rules here (it's not explicitly mentioned in the docs), but it seems like Obsidian only treats a string with a # as a tag if it stands alone, e.g. some kind of word-boundary in there:
