[Component governance] Update Azure.Identity dependency

[javiercn]

Updates the Azure.Identity version.

FYI I know SqlClient are working to update the dependency on its side, and we don't usually take direct dependencies on their transitive dependencies. But it may be justified in this case...

@javiercn What are the circumstances here that mean we should add an explicit reference to the transient rather than updating the direct dependency? (If the direct dependency isn't updated yet, then that's something that needs to be done on SqlClient so that it can flow through to here.)

I'm not a nuget dependency expert, but it looks like 5.1.1 is the newest version of SqlClient and it depends on Azure.Identity 1.7.0 (or newer?).

[amcasey]

But: dotnet/SqlClient#2189

[ajcvickers]

Right. SqlClient needs to ship a new package, then we can depend on that.

[ErikEJ]

And it needs to be a LTS version I guess?

[ajcvickers]

Fixed by #32187

[ErikEJ]

@ajcvickers how fixed? 5.1.2 does not include an update..

[ajcvickers]

There is nothing to track here. We will not be taking a direct dependency on Azure.Identity. This was discussed in Tactics.
