Showcase CI check fails due to removed BUILD.bazel in sdk-platform-java

[diegomarquezp]

googleapis/sdk-platform-java#1935 removed the showcase BUILD file, and now the script that manipulates such BUILD file is failing.

[diegomarquezp]

This section assumes the existence of BUILD.bazel in sdk-platform-java/showcase

spring-cloud-gcp/spring-cloud-generator/scripts/generate-showcase.sh

Lines 79 to 81 in 54ebcde

	# Modify sdk-platform-java/showcase/BUILD.bazel
	buildozer 'new_load @spring_cloud_generator//:java_gapic_spring.bzl java_gapic_spring_library' BUILD.bazel:__pkg__
	modify_build_file "BUILD.bazel"

It adds a java_gapic_spring_library rule

spring-cloud-gcp/spring-cloud-generator/scripts/generate-steps.sh

Line 119 in 54ebcde

buildozer "new java_gapic_spring_library $SPRING_RULE_NAME" ${path_to_build_file}:__pkg__

The implementation of java_gapic_spring_library produces the following protoc command:

We need to replace the bazelisk call with something similar to the hermetic build script
