Metadata Query docs/proto-docs section not formatting correctly

[dwedul-figure]

Summary of Bug

The Metadata v1 Query section of docs/proto-docs.md is not being generated correctly.

The queries have several lines of comments and it looks like the auto-gen stuff isn't handling it correctly.

The protocgen.sh script is responsible for automatically generating that file whenever make proto-gen is run (along with the go files).

Version

1.5.0

Steps to Reproduce

Navigate your browser to https://github.com/provenance-io/provenance/blob/main/docs/proto-docs.md#provenance.metadata.v1.Query and note that formatting is correct for 1 line, but breaks on the 2nd until the end of that section.
