updated environmentId in build-test action

[arpavan]

Description

Test Engine GitHub Action "Build and Test" had begun to fail persistently, and the reasoning behind this was found to be that 1) the sample apps being used in the test run workflow file were missing from the test tenant, and 2) the environment ID was found to be incorrect.

The sample apps have been reuploaded to the tenant again, and this PR corrects the environment ID that was being used to execute this workflow.

PR checks are still failing due to one missing sample app (pcfcomponent) required for tests to run. Publishing this app to the environment errors out with this error, despite having turned on the required setting to allow this -
