docs: replace version badges with comments in repo-level atlantis.yaml example

[jamengual]

Summary

Replace HTML badge elements with clean YAML comments in the 'Example Using All Keys' section of the repo-level atlantis.yaml documentation to improve readability while preserving version information.

Changes Made

• Converted HTML badges to comments: Replaced <Badge text="vX.X.X+" type="info"/> with # Available since vX.X.X
• Improved readability: The YAML example is now much cleaner and easier to read
• Maintained version info: All version information is preserved as inline comments
• Better copyability: Users can now easily copy the YAML without HTML elements

Before vs After

Before:

version: 3 <Badge text="v0.1.0+" type="info"/>
automerge: true <Badge text="v0.15.0+" type="info"/>

After:

version: 3 # Available since v0.1.0
automerge: true # Available since v0.15.0

Motivation

The HTML badge elements made the YAML example cluttered and less readable. Converting to comments:

• Maintains all version information
• Improves code readability
• Makes the example easier to copy/paste
• Keeps version badges only in server configuration docs as intended

Impact

• Documentation: Cleaner, more readable YAML examples
• User Experience: Easier to copy and understand configuration options
• Consistency: Version badges now only appear in server configuration docs
• No Breaking Changes: Pure documentation improvement

Files Changed

• runatlantis.io/docs/repo-level-atlantis-yaml.md: Updated "Example Using All Keys" section
