Signed-off-by: Alejandro Gómez [email protected]

Description of the change

There are problems related to the size of the index.yaml, so we have decided to drop releases older than 1st June, 2022, which reduces the size from +6.7MB to 3.2MB

Benefits

• Faster repo updates and maintainability.
• Remove deprecated apps.

Possible drawbacks

• Possibly miss some old app versions
• The chart packages are not being removed, so they can still be downloaded.
• The commit previous to the commit that merges this PR will still be in the Git history.

Checklist

• All commits signed off and in agreement of Developer Certificate of Origin (DCO)
