Updated the workflow for bumping Helm chart versions

[durgesh-ninave-crest]

Description

• Updated the existing GitHub Action workflow to update Both Helm chart versions (bump_charts_version).
• Added a new GitHub Action (bump_staging_chart_version) specifically to update the manifest_staging Helm chart with the latest changes merged into main

Working

1. bump_charts_version workflow:

• Triggered when a new release branch (release-x.x or release-x.x.x) is merged into main.
• This workflow updates the Helm chart versions for both main and manifest_staging using the latest release tag.

2. bump_staging_chart_version workflow:

• Triggered when any branch is merged into main, except if the branch name starts with release.
• After the merge, it creates a new build with the latest tag and updates the manifest_staging Helm chart with the corresponding version and tag.
