test: detox black list gas api endpoint (#11096)

<!--
Please submit this PR as a draft initially.

## **Description**

The end to end tests hang on the login view because they wait for the
app to complete requests to the gas endpoint. Sometimes, the tests fail
because of this, which creates instability and causes builds on Bitrise
to fail. Additionally, this might be causing a slight increase in build
run times. The solution should be to blacklist the gas endpoint.
