New addon v2 creates in `test-app` file `ember-cli-update.json` with option `--ci-provider=travis`

[mkszepp]

While creating a new ember addon V2 i have seen, that in blueprint there was added travis.

Travis CI is was deprecated in v5 see https://deprecations.emberjs.com/ember-cli/v5.x/#toc_travis-ci-support

Steps to reproduce:

1. ember addon my-addon -b @embroider/addon-blueprint --pnpm
2. open ´ember-cli-update.json->--ci-provider=travis` is present

Maybe this lines are doing that... https://github.com/embroider-build/addon-blueprint/blob/eef35575e7130ffe3b588ecd83c637f35fa56220/index.js#L178-L196

Output of addon generate:

hm, seems goofy -- we should probably set ci-provider to none. would you be willing to submit a PR trying that?
