Install fails if python is not installed

[mskri]

After updating to [email protected] when trying to install knip in an environment (i.e. docker) where you don't have python installed you get an error. The readme doesn't seem to indicate that having python installed is a requirement. Not sure if this is a bug report or a request to update the readme?

That's a bit of a surprise. I've replaced bash-parser with tree-sitter-node + tree-sitter-bash in v2.19.6. Didn't notice this in their docs and this wasn't clear to me when adding it to Knip.

I've opened tree-sitter/tree-sitter-bash#188 over there, maybe it's just an overlook with their v0.20.0 release (I could downgrade to v0.19.0 if necessary).

Update: tree-sitter/tree-sitter-bash#134 (comment)

I've downgraded the dependency in v2.19.8 so we don't need to wait it out. It should fix the issue, let me know if that's not the case.

Guess this wasn't the right time for tree-sitter yet. Reverted to bash-parser in v2.19.11.
