Short description

We have a warning_tag in ui.py currently, which is super helpful. In dbt-labs/dbt-core#9886 we found that we needed an error_tag function as well. We added it to core temporarily as a stop gap, but it really should be provided by dbt-common instead.

Acceptance criteria

dbt-common provides a error_tag similar to warning_tag

Suggested Tests

string checking
