chore(ci): update layer version for all AWS partitions in docs (#7757)

fix(ci): update layer version for all AWS partitions in docs

Fixes #7650

This extends the fix from #6868 to handle all AWS partitions, not just
commercial AWS. The previous fix only updated layer ARNs with specific
python versions (e.g., python312) but missed the template placeholders
with {python_version} for China and GovCloud partitions.

Changes:
- Updated hardcoded layer versions from :18 to :27 in docs/index.md
- Extended update_layer_arn_v3.sh to handle AWS China (arn:aws-cn)
  and GovCloud (arn:aws-us-gov) layer ARNs
- Added sed patterns for both specific versions and {python_version}
  placeholders across all AWS partitions

The automation now correctly updates layer versions for:
- Commercial AWS: arn:aws:lambda:{region}:017000801446:layer:...
- AWS China: arn:aws-cn:lambda:cn-north-1:498634801083:layer:...
- GovCloud East: arn:aws-us-gov:lambda:us-gov-east-1:165087284144:layer:...
- GovCloud West: arn:aws-us-gov:lambda:us-gov-west-1:165093116878:layer:...
