Do we still need the typescript-json-schema dependency?

Nobody has claimed this yet.

# Question
It does not seem to be used anymore and the `typescript-json-schema` command it provides is not working and from what me and @phanlezz could gleam hasn't been working for a long time.
The only use in code was in a test file from 2020 for the git log parser, and https://github.com/MaibornWolff/codecharta/pull/860 mentiones it, but we are unsure if that use case still exists.

## Question

Inspect current references to the typescript-json-schema dependency and the 2020 git log parser test mentioned in the issue, then review pull request #860 for the historical use case. Confirm whether the command or dependency is still needed; done means removing it if unused, or documenting the remaining use if it is required.
