[NETE2ESDK] [Azure Linux ARM64] Installing .NET 10 alpha SDK in Mariner2 ARM64 2.0 or Azure Linux ARM64 3.0 should not depend on package netstandard-targeting-pack-2.1

[ChenhuiYuan01]

Repro steps:

1. Prepare Mariner2 ARM64 2.0 or Azure Linux ARM64 3.0 in Dokcer via running
   sudo docker run -it -v ~/tmp:/root/workspace mcr.microsoft.com/cbl-mariner/base/core:2.0 sh
   or
   sudo docker run -it -v ~/tmp:/root/workspace mcr.microsoft.com/azurelinux/base/core:3.0 sh

2. Try to install 10.0.100-alpha.1.24616.9 SDK via installer *.cm.2-aarch64.rpm

Expected:
SDK installed successfully.

Actual result:
SDK install failed as depending on package netstandard-targeting-pack-2.1

Note:

1. This SDK could be installed successfully in Mariner2 X64 2.0 and Azure Linux X64 3.0
   
   

2. Net9.0 could be installed successfully in Mariner2 ARM64 2.0 and Azure Linux ARM64 3.0

@dsplaisted @dotnet/source-build-triage to see if others are more knowledgeable about how this worked in 8/9 versus 10 for those platforms.

@NikolaMilosavljevic for input.

We have modified the RPM build recently, this might be one of the side-effects. I believe arm64 SDK should not have a dependency on netstandard-targetingpack-2.1.

Will take a look and prepare a fix.
