feat: upgrade changes

[niladrih]

Changes to upgrade.

Description

Changes:

1. upgrade-job now does not use the semver::VersionReq API. Instead uses lt, gt, ge, le, eq operators to judge order of version. This is because VersionReq doesn't accurately reflect order when comparing stable versions with pre-release ones (https://internals.rust-lang.org/t/changing-cargo-semver-compatibility-for-pre-releases/14820/9).
2. Add pre-flight check failure in the kubectl-mayastor plugin when a stable version tries to upgrade to an unstable one. This can be avoided with the --allow-unstable flag. The existing flag --skip-upgrade-path-validation-for-unsupported-version also skips this check.
3. Add pre-flight check failure in the kubectl-mayastor plugin when the source version is higher (semver) than the target.
4. Avoid running the publish_chart_yaml.sh script for v2.5.0-0-main-unstable-<timestamp>-0 alongside the usual tag 2.5.0-0-main-unstable-<timestamp>-0.
