Use latest jdk available in VMR aspnetcore build

[ViktorHofer]

All VMR and aspnetcore repos builds are currently broken

Our build images got updated yesterday and with that, the installed jdk versions changed significantly (across major versions). This broke aspnetcore's build which asserts on a very specific version.

I reached out to @wtgodbe in dotnet/aspnetcore#58465 (comment) to better understand why they had to change back to a an exact version match instead of just depending on a specific major version.

This patch tries to use whatever latest version is available by using "latest". Let's see if that works.

OK that didn't work:

OK the patch works in dotnet/aspnetcore#59788. I will wait until the sync is complete and then fast merge to unblock the broken builds.

dotnet/aspnetcore#59794 - I'm in favor of running init-tools-native in CI as well
