ci: exclude scipy, sqlachemy, pandas from groups updates

[kenibrewer]

Description

The most recent dependabot groups PR failed due to changes in pandas. Due to the importance of pandas and scipy to the pycytominer codebase and a higher likelihood of breaking changes, I propose we separate them from the grouped updates.

What is the nature of your change?

• Bug fix (fixes an issue).
• Enhancement (adds functionality).
• Breaking change (fix or feature that would cause existing functionality to not work as expected).
• This change requires a documentation update.

@d33bs Any other high risk packages we want to identify at this time? Alternately, we could just merge a smaller set of excludes, and monitor if other packages regularly cause problems.
