The current `MarkupSafe` pinned version has been added in dbt-labs#4746 as a
temporary fix for dbt-labs#4745.

However, the current restrictive approach isn't compatible with other
libraries that could require an even older version of `MarkupSafe`, like
Airflow `2.2.2` [0], which requires `markupsafe>=1.1.1, <2.0`.

To avoid that issue, we can allow a greater range of supported
`MarkupSafe` versions. Considering the direct dependency `dbt-core` has
is `Jinja2==2.11.3`, we can use its pinning as the lower bound, which is
`MarkupSafe>=0.23` [1].

This fix should be also backported this to `1.0.latest` for inclusion in
the next v1.0 patch.
