Add GitHub Actions workflow to automate release creation on tagged pushes (#7209)

* feat(workflows): add GitHub Action to create release on new tag

This workflow automates the release creation process whenever a new
tag is pushed to the repository. It checks if a release for the tag
already exists and creates one if it doesn't, enhancing the release
management and streamlining the deployment process.

* test

* fix(workflow): improve release existence check in release-on-tag.yml

Refactor the script to improve checking for existing releases by tag.
Return an object instead of using core.setOutput to streamline the
workflow logic. Also, set result-encoding to string for better
compatibility.

* fix(workflow): correct output handling in release-on-tag.yml

Corrected the output handling in the 'release-on-tag.yml' workflow file
by changing 'result-encoding' to 'outputs'. This ensures that the step
correctly checks if a release exists before attempting to create a new
one, thereby avoiding potential errors during the release process.
Added a blank line for better readability.

* fix(workflow): correct output setting in release-on-tag workflow

Refactored how the release_exists output is set to be compatible with
GitHub Actions syntax. This ensures the workflow reliably detects if
a release already exists, improving the robustness of the release
process.

* fix(release): correct output handling in release-on-tag workflow

Improved the way outputs are managed in the 'check_release' step by
returning values instead of direct assignments. This change ensures
better handling of release existence checks and improves code
readability. Added 'result-encoding' to specify string encoding for
results.

* fix(workflow): correct release existence check and add debug output

Refactored the release existence check to return a simple boolean
string ('true'/'false') rather than an object. Added a step to print
the release existence status for debugging purposes. This ensures
correct conditional evaluation and aids in troubleshooting workflow
issues.

* fix(workflow): simplify release process by removing redundant checks

The release-on-tag workflow has been streamlined by eliminating the
redundant steps checking for existing releases. This change reduces
complexity and speeds up the release process by directly creating a
release on every tag push without prior existence verification.
