Run cloud integration tests if experimental/ssh files are changed (#4577)

## Changes
<!-- Brief summary of your changes that is easy to understand -->

Push workflow now triggers integration tests if there is a
`test-exp-ssh` target detected for the changed files

## Why
<!-- Why are these changes needed? Provide the context that the reviewer
might be missing.
For example, were there any decisions behind the change that are not
reflected in the code itself? -->

Without this change the integration tests are not triggered for pull
requests that only change experimental/ssh files (or acceptance tests
for them). This is not correct since experimental ssh project does have
acceptance tests that run in the cloud.

## Tests
<!-- How have you tested the changes? -->

Created a PR to this PR and verified that the integration tests are
triggered for it: #4579

<!-- If your PR needs to be included in the release notes for next
release,
add a separate entry in NEXT_CHANGELOG.md as part of your PR. -->
