Inconsistent capitalization and verb tense in Alembic migration descriptions

What happened and how to reproduce it?

Well, this is more of a nitpick and not that important, but there are quite a few inconsistencies in Alembic migration descriptions that I noticed.

1. Some migration descriptions start from a capital letter, some from lower case letter

Revision	Description
53ff648b8a26	Add revoked_token table. ✓
e79fc784f145	add timetable_type to dag table for filtering. ✗

2. Some migration descriptions use imperative mood (Add, Remove, Fix) while a few deviate (Added/Adding):

Revision	Description
c4602ba06b4b	Added DagPriorityParsingRequest table. ✗
8e1c784a4fc7	Adding max_consecutive_failed_dag_runs column to dag_model table. ✗

What you think should happen instead?

Proposed standard:

• Start with a capital letter
• Use imperative mood (Add, Remove, Fix, Rename, etc.)

This matches what the majority already follows and is consistent with Git commit message conventions.

A note in the contributor guide or a simple lint check could prevent this from drifting further.
