feat: add custom crates version suffix support

[antonbaliasnikov]

What ❔

• Add custom suffix support for the workspace version.
• Add capability to update Cargo.lock for other workspaces

Why ❔

Sometimes it is required to add a suffix to the crates version. As release-please is unable to properly work with prereleases and support suffixes and fails to update only version part (it removes a part of the suffix with each update), the proposed solution is to update Cargo.toml workspace version separately just before Cargo.lock updates and commit changes together to the release PR.
