[morph.ai] Fixed PLAYGROUND-PR-3301 -- Fixed CSS inline comments highlighting regression

[MorphCodeBot]

Fixed an issue where inline block comments within CSS property values were not being properly highlighted. This was a regression introduced in version 10.6.0.

Changes:

• Added hljs.C_BLOCK_COMMENT_MODE to the contains array in the attribute values section
• This allows for proper highlighting of /* */ style comments within CSS property values

Before:

• Block comments within property values were not properly highlighted
• This affected code using the new highlightAll API introduced in 10.6.0

After:

• Block comments are now correctly highlighted in all contexts
• Behavior now matches what was present in version 10.5.0

Tested:

• Verified fix with provided test cases
• Confirmed proper highlighting of inline comments in CSS property values
