fix(ci): add missing dollar signs in SSM parameter path variables (#7695)

Fixes #7689

When adding Python 3.14 support in commit a58cef7, the SSM parameter
creation workflow was refactored to use environment variables instead
of GitHub Actions expressions. However, 10 out of 12 lines were missing
the dollar sign ($) prefix on the PACKAGE_VERSION variable.

This caused version 3.23.0 SSM parameters to be created with the literal
string 'PACKAGE_VERSION' in the path instead of the actual version number.

For example, instead of:
  /aws/service/powertools/python/x86_64/python3.13/3.23.0

The workflow created:
  /aws/service/powertools/python/x86_64/python3.13/PACKAGE_VERSION

This affected:
- ARM64: Python 3.11, 3.12, 3.13, 3.14 (4 versions)
- x86_64: Python 3.9, 3.10, 3.11, 3.12, 3.13, 3.14 (6 versions)

Only ARM64 Python 3.9 and 3.10 worked correctly.

Verified by checking AWS SSM - the incorrectly named parameters exist
and the correctly named version parameters are missing.
