[Task] Fix the workflow for PHP release to automatically upload the .tgz file to the release page for PECL to work.

[prateek-kumar-improving]

Description

Currently, the workflow compresses the .tgz valkey-glide package inside a .zip and does not upload the .tgz package to the release page for the PECL command to work.
We need to find a way to make this upload work from the workflow or directly from the tag release.

For this issue: #152, we uploaded the .tgz file manually to fix the PECL installation but for new releases we will need to ensure that this happens in the workflow.
