dev: Add CI doc prettier check to local `rust_lint.sh`

[2010YOUY01]

Which issue does this PR close?

A small step towards https://github.com/apache/datafusion/issues/19227

Rationale for this change

What changes are included in this PR?

• Move doc prettier check command to a local script
• Add this script to the lint-check runner dev/rust_lint.sh to make local development easier (Technically it's neither rust nor lint, but keeping all non functional tests here seem to be the most convenient.)

Are these changes tested?

Are there any user-facing changes?
