Deploy app on s3gw

• installEpinio function modifed, now it accepts optional s3Storage: Cypress.env('s3Storage') string values s3gw, s3, and "" aka none , booleans args for setting s3 and s3gw were removed
• fixed also selector for aws s3 in the same function but it is not used anywhere (but works, can be used in https://github.com/epinio/epinio-end-to-end-tests/issues/236)
• existing workflow for Rancher-UI-1-Chrome extended for triggering another job related to s3gw where only applications.spec.ts with tag @appl-1 (simplest app depoloyment test) is used
• the workflow is using different runner classes for the jobs so it should not slow down the execution time (jobs are running in parallel)

Testrun: https://github.com/epinio/epinio-end-to-end-tests/actions/runs/5832019579

Command used for the test development and testing (only installation.spec.ts part in rancher):

S3_STORE_TYPE=s3gw CACHE_SESSION=true CORS=1.2.3.4.nip.io UI=rancher CLUSTER_NAME=local \
SYSTEM_DOMAIN=1.2.3.4.nip.io RANCHER_USER=admin RANCHER_PASSWORD=[SECRET] \
RANCHER_URL=https://1.2.3.4.nip.io/dashboard EPINIO_PASSWORD=[SECRET] \
npx cypress run --config-file=cypress.config.ts -b chromium --headed --spec cypress/e2e/unit_tests/installation.spec.ts

I rechecked this in CI and seems to be working fine. Tested also locally with the above-mentioned new flags and observed the s3gw selection.

These are just a few non-blocking comments to be discussed/treated later.

• I may be wrong, but it seems that exported videos are available only for the minio case. We may want to extend this to s3gw as well.
• Test name differentiation s3gw/minio/other may be also nice.
• Experimental Rancher workflows seem to fail (link). It seems to need some updates.

Nice job. Approving pr.
