Travis CI builds disabled due to negative credit balance

The Travis-CI build badge in the README reports an error, possibly due to the travis-ci.org -> .com switch. It looks like the .travis.yml file is only included for legacy reasons, so should the README badge be removed?

From the README:

[![Travis Build Status](https://travis-ci.com/manubot/rootstock.svg?branch=main)](https://travis-ci.com/manubot/rootstock)

So it looks like we've already fully switched from travis-ci.org -> .com.

When I login to Travis and go to https://app.travis-ci.com/github/manubot/rootstock, I see:

Builds have been temporarily disabled for public repositories due to a negative credit balance. Please go to the Plan page to replenish your credit balance or alter your Consume paid credits for OSS setting.

I'm wondering whether we should remove Travis support entirely, since it's a lot of support effort and now requires payment without any unique benefit. @agitter wdyt?

Exactly. I don't see any reason to use it for a new manuscript. I'm okay removing Travis support entirely. We would need to update SETUP.md in several places to note it is no longer supported and remove the setup instructions.

Existing projects using Travis CI could be affected if we delete .travis.yml and they update rootstock without looking at the merge carefully. We could help users restore that file if they get stuck. I can't think of a better way to avoid removing the file if it is in use.

Yeah! Happy to help legacy users upgrade to GitHub Actions. I imagine there are not too many active manuscripts still using Travis, especially now that it's a paid service.
