Supporting dotnet 10.0 preview version (#1305)

* Supporting dotnet 10.0 preview version

* Changing the test to fetch actual LTS version.

* To resolve the conflict

* To resolve conflict again

* Version bump and adding back the azureedge url's as those should be removed by the automated version update PR

* To resolve conflict again

* Final version bump

* Reverting back the test script change as created separate PR for that.

* Ubuntu EOL changes and additional info about dotnet 10.0-preview version.

* Correcting the comment.

* Updates based on review comments to use '-preview' in the label as suffix.

* Removed reame file change as suggested.

* Update src/dotnet/README.md

* Inconsequential change to rerun the failed test
