Fix Conda update script for missed packages from previous release

[jenny (JennyPng)]

• handle some edge cases that caused inconsistencies in this generation Conda Release 2026.09.01 generated by 6743806 #48737
  • a new mgmt library azure-mgmt-trustedsigning has no setup.py/pyproject.toml (it's also deprecated) - it fails one of the inner steps, but still got added to conda-sdk-client.yml - update to prefilter out packages that dont have pyproject.toml/setup.py
  • ensure that release log versions are consistent with versions in conda sdk client yml, by specifically using the yml as a source of truth input to the release log update functions
  • an old data plane package never had a release log ? update release log creation to check for existence of release log for all data plane pkgs, not just 'outdated' ones
  • some packages were released before the previous Conda release date, but released after the script ran, so they were excluded and caused version inconsistencies across files on this run --- check all existing versions in the conda yml against the csv versions, not just 'outdated' packages
  • add some basic unit tests for the update script
