Documentation: include . in the example commands

I wasn't able to get the typechecking to run without the .

❯ scip-ruby --index-file index.scip
You must pass either `-e` or at least one folder or ruby file.

  -e string      Parse an inline ruby string (default: "")

Do you run into this issue with bundle exec too or just direct invocation? For bundle exec, it does seem to work fine for me. 🤔

bash-5.1$ bundle exec scip-ruby --index-file index.scip --gem-metadata "brew@3.5.9"
No errors! Great job.

Same for direct invocation of scip-ruby:

❯ ~/Code/scip-ruby/bazel-bin/main/scip-ruby --index-file index.scip --gem-metadata "brew@3.5.9"
No errors! Great job.

What scip-ruby version are you using?

Can you share the output of env too?

Ah, OK. Narrowed this down. This seems to be needed when the sorbet/ folder is not present. I will create an updated PR to document this, closing this one.
