Although this may be a useful feature, it doesn't actually help with the original issue I'm afraid. This is very likely because I did not explain it properly.

The place we need the plan only options is here: https://github.com/Azure/accelerator-bootstrap-modules/blob/d955b911ff469c14a99e783eccbd75c1ac94b69b/.github/workflows/end-to-end-test.yml#L335

We basically just need to skip the CD part:

• https://github.com/Azure/accelerator-bootstrap-modules/blob/d955b911ff469c14a99e783eccbd75c1ac94b69b/.github/workflows/end-to-end-test.yml#L356
• https://github.com/Azure/accelerator-bootstrap-modules/blob/d955b911ff469c14a99e783eccbd75c1ac94b69b/.github/workflows/end-to-end-test.yml#L377

Add a planOnly flag to the matrix here to support it: https://github.com/Azure/accelerator-bootstrap-modules/blob/d955b911ff469c14a99e783eccbd75c1ac94b69b/.github/tests/scripts/generate-matrix.ps1#L5

Can we just make the a second if statement for readability since the two options are not directly related?
