fix(csp): add exceptions for ANDI A11y Tool

[billhimmelsbach]

We helped the ITAP team over in RegTech make some exceptions to our CSP during testing so they could use the ANDI accessibility tool for their accessibility audits, and they were hoping they could also run it on cf.gov. This PR adds the few CSP tweaks they need for the tool to start working.

You can see the current CSP issues by following the "How to test this PR" steps or take a peek at the screenshots.

Closes #8541
