Fix PHP SDK version persistence and validation

Issue

The PHP packagist publishing workflow was failing with a version validation error:

"./composer.json" does not match the expected JSON schema:
- version : Does not match the regex pattern ^v?\d+(\.\d+){0,3}|^dev-

The version field in composer.json was being reset to empty, causing validation failures.

Fix

• Set the version back to "0.1.0" in the PHP SDK composer.json file
• Modified the workflow to handle empty or invalid version values:
  • Added validation to check for empty versions and set a default of "0.1.0"
  • Added regex validation to ensure version format matches the required pattern
  • Updated version bumping logic to handle edge cases

Testing

The fix should be verified when the workflow runs on the next push to main that affects the PHP SDK.
