Add file-overrides to the try config

[NullVoxPopuli]

When supporting wide ranges of ember versions, like 3.28 to 6.1, sometimes config changes to various files may be needed to better simulate what folks would have in their actual apps.

For example, with the 6.1 blueprint, ember-qunit v9 is used, and that requires a different tests/test-helper.js / .ts, so it would be handy for me to be able to specify different contents for that file for the 6.1 scenario that I'm building.

Would using dependencySatisfies in test-helper.js work to conditionally use the different test setup?

[NullVoxPopuli]

it would, but I don't want to spread my compatibility stuff across a whole project -- I'd like to all be centralized in ember-try config
