Add CI test-integrations job for connect Vault CA provider (#6949)

* vault-ca-provider: add make target and CI test-integration job for /agent/connect/ca/ Vault Provider tests

* load env vars in the vault-ca-provider ci job

* add checkout task, see if we need to attach workspace or not

* ci: remove vault dependency from go-test job to ensure we only run the vault-provider tests in their job

* ci: fix from RB and Alvin code review, add mod cache after checkout

* ci: add CI context to make target and store test results

* ci: fix whitespace

* ci: create test results directory before we try to write to it
