chore(ci): check e2e main commits against Android API level 27 (#6031)

### Description

We want CI to check the app against the highest and lowest supported
Android API levels. The highest supported API level is being checked in
the PR CI. The lowest level should be checked after merging the PR into
a main branch.

Currently, the lowest API level we support is 24, but the levels 24, 25,
and 26 are failing the CI for some reason.

Setting Android API level 27 as the lowest one for now.

* 24 is failing due to Let's Encrypt root certificate expiration
* 25 is failing (RET-1274 to investigate)
* 26 is failing (RET-1275 to investigate)

### Test plan

CI succeeds, like in this workflow:

### Backwards compatibility

### Network scalability
