Provide the option for passing env variables to the Publish to Ballerina Central workflow

[tharindu-nw]

Current Limitation

All the stdlib and connector publishing workflows refer to the same template in the library repo. Currently it only takes inputs to provide additional flags for gradle build and publish steps. There are instances where we need to set other environment variables for debugging purposes. For instance, we enable debug logs for the central client by setting CENTRAL_VERBOSE_ENABLED=true. This is not possible with the current setup.

Suggested Improvement

Provide an optional input argument like additional-env-variables similar to:

ballerina-library/.github/workflows/dev-stage-central-publish-connector-template.yml

Lines 9 to 12 in d57cfd9

	required: false
	type: string
	default: ""
