fix: comment filter now works correctly

The issue was that we were overriding the default comment filter settings
with incorrect values. The vscode-emmet-helper library uses special template
placeholders like [#ID] and [.CLASS] in the comment.after setting, which we
were replacing with simple strings.

By removing filter.commentTrigger, filter.commentBefore, and filter.commentAfter
from our default config, the library now uses its correct default values that
include the template placeholders needed for comment generation.

Changes:
- Removed incorrect default values for comment filter settings
- Un-skipped the comment filter test which now passes
- All 69 tests now passing
