release: bump versions

Bump abnf_to_pest from 0.5.1 to 0.6.0 (minor) for the upcoming release
that brings:

- support for ABNF incremental alternatives (`=/`, RFC 5234 §3.3)
- predefined ABNF core rules (RFC 5234 §B.1)
- the abnf 0.13.0 upgrade with its API adaptation

Update src/lib.rs html_root_url accordingly.
