fix(cicd): use dev- prefix for pre-release tags to avoid polluting release-please

Pre-release tags on develop used v* prefix (e.g. v0.33.1-rc.60) which
release-please interpreted as the latest version, causing it to generate
wrong release versions. Changed to dev- prefix (e.g. dev-0.34.0-rc.61)
so release-please only sees stable v* tags.

Cleaned up: 42 RC releases and tags deleted.
