Remove redundant process.env assignment that doesn't handle multiline values properly. The @actions/core.exportVariable() function already handles environment variable setting with proper EOF delimiters for multiline content. Add comprehensive test cases for multiline output handling that verify: - Multiline output with setOutput - Multiline output with exportVariable - Special characters in multiline output Update existing test to reflect that process.env should not be set directly.

The jq action was directly assigning to
process.env[env_var]before callingcore.exportVariable(), which breaks multiline values since direct assignment doesn't use EOF delimiters.Changes
