CI workflow: error uploading artifacts & commiting release notes and version

[akordowski]

Description

The CI.yml workflow throws the following error:

Error: Failed to CreateArtifact: Received non-retryable error: Failed request: (409) Conflict: an artifact with this name already exists on the workflow run

I was able to track it down to this matrix:

gh-gei/.github/workflows/CI.yml

Lines 18 to 20 in b380004

	matrix:
	runner-os: [windows-latest, ubuntu-latest, macos-latest]
	language: [ csharp, actions ]

As the artifacts are uploaded during the actions step the conditions on the upload setps must be changed

from:
if: always() && matrix.runner-os == 'ubuntu-latest'

to:
if: always() && matrix.runner-os == 'ubuntu-latest' && matrix.language == 'csharp'

This fixes the error and the artifacts are uploaded only once.

There is also an error while commiting release notes and version. This is caused by the persist-credentials: false setting on the checkout (see here).

gh-gei/.github/workflows/CI.yml

Lines 285 to 289 in b380004

	- uses: actions/checkout@v4
	with:
	persist-credentials: false
	token: ${{ secrets.RELEASE_NOTES_PAT }}
	fetch-depth: 0

I removed the setting in the provided PR and also updated the version of the actions.
