Fix {{role}} CBS support to custom HTML (#657)

# PR Checklist
- [ ] Did you check if it works normally in all models? *ignore this
when it dosen't uses models*
- [v] Did you check if it works normally in all of web, local and node
hosted versions? if it dosen't, did you blocked it in those versions?
- [v] Did you added a type def?

# Description
This pull request adds `{{role}}` support to the recently introduced
Custom HTML feature. Although documentation indicated that CBS was
supported in Custom HTML, the `{{role}}` CBS was returning `null`
instead of rendering the intended values.

## Changes
By passing `getCbsCondition()` as the second argument to
`risuChatParser`, `{{role}}` now renders as expected in Custom HTML,
allowing users to apply conditional logic based on roles.

If there is an alternative way to enable `{{role}}` support in Custom
HTML without this modification, feel free to close this PR. Thanks for
checking it out!
