rs-release.yml

# This workflow is triggered by a tag that matches the pattern rs/v*-pin.
# Essentially it does the following:
#   - gathers release info including its version using created tag
#   - applies version to the workspace and updates crates dependencies
#   - runs all tests before going further
#   - builds assets for the release: IDL Parser for WASM
#   - publishes 'sails-*' crates to crates.io
#   - amends contract template with the new version and runs tests against it
#   - crates PR with the changes, release tag and draft release
# Merging PR and pubslishing release is supposed to be done manually.
