Send "urgent tickets" CSVs

[dav3r]

🗣 Description

This PR modifies cyhy-mailer to attach the new "urgent tickets" CSVs (instead of the previous "critical" and "high" CSVs) when emailing the Cyber Exposure (CybEx) scorecard.

While I was here, I updated the pre-commit config and a couple of related changes (see commits 8fef4c7, fc34ca5, d396e61).

💭 Motivation and context

• This PR is dependent on the changes in BOD 22-01 / KEV changes cyhy-reports#72 and Support "urgent tickets" queries ncats-webd#27 and is blocked until they are deployed
• This PR resolves Update cyhy-mailer to only send 2 new CSVs based on urgency cyhy-system#50
• This PR covers part of the work requested in Update the open/closed “tickets” CSVs that accompany the Cybex Scorecard  cyhy-system#34

🧪 Testing

I tested this change by temporarily modifying the default email/BCC addresses to point to my email address, then ran this command:

$ AWS_DEFAULT_REGION=us-east-1 AWS_PROFILE=my_email_sending_profile cyhy-mailer cybex \
--cybex-scorecard-dir=test_scorecards/ --db-creds=./secrets/db-creds.yml --summary-to=me@myemail.gov

After I ran that, I confirmed that I received an email containing the new "urgent tickets" CSVs (that I had previously generated while testing cisagov/cyhy-reports#70).

I also verified that there were no failures when I ran pytest.

Everything functionality wise looks good. On the back of my comments please make sure to run a pre-commit run --all-files to make sure the updated pre-commit configuration is applied to this repository since there is no GitHub Actions testing.
