chore(pr/branch): update branch variable references to branch_slug

[saidsef]

This pull request updates the chart to use the new branch_slug variable for preview environments and image tags, replacing the previous branch variable. It also adds branch_slug to the GitHub and GitLab PR/MR templates and updates the chart version. The changes ensure consistency and clarity when referencing branch names in preview deployments.

Branch slug variable improvements:

• Updated charts/applicationset/values.yaml to use {{branch_slug}} instead of {{branch}} for image tags and preview environment values in both GitHub and GitLab repositories. [1] [2] [3]
• Updated comments in charts/applicationset/values.yaml to reference {{branch_slug}} for dynamically passing the branch of the pull request head.

Template enhancements:

• Added branch_slug as an environment variable in both GitHub PR (charts/applicationset/templates/github-pr.yml) and GitLab MR (charts/applicationset/templates/gitlab-mr.yml) templates. [1] [2]

Chart metadata updates:

• Bumped chart version to 0.17.2 in charts/applicationset/Chart.yaml.
• Updated chart change log annotation to document the addition of branch_slug to info sections in GitHub and GitLab PR templates.
