Add dynamic placeholder replacement in functions.tmdl (#1)

Introduce a new workflow step in `publish-abcclassification.yml`
to replace placeholders for package ID and version in the
`functions.tmdl` file. Updated `functions.tmdl` to use
placeholders (`__PLACEHOLDER_PACKAGE_ID__` and
`__PLACEHOLDER_PACKAGE_VERSION__`) instead of hardcoded values
for `DAXLIB_PackageId` and `DAXLIB_PackageVersion`. This ensures
metadata is dynamically updated during workflow execution.
