[YuliiaKovalova]

We are locking down for 17.8 and main will become 17.9.

Build is failing in a manner that's very likely unrelated to your changes @YuliiaKovalova.

@dotnet/dnceng did someone make changes somewhat recently that may now cause the error below❔

not sure if this is the best way to track this however

• build #20230707.3 • Bump Microsoft.Rest.ClientRuntime (#900) succeeded
• build #20230823.1 • Merging Docker image info updates from build failed
• every later build of the dotnet-versions-public-ci pipeline also failed
