Request to add support for .Net 9

[md-owes]

Feature request type

enhancement

Is your feature request related to a problem? Please describe

It's been more than a month since .Net 9 was released and my application has been migrated to .Net 9 but due to Garnet, i am still forced to use .Net 8. Can this be upgraded in the next release.

Describe the solution you'd like

Garnet should be able to run on a system that has only .Net 9 installed

Describe alternatives you've considered

Alternative would be to have multiple installations of .Net (v8 and v9) on my Apple Macbook so that my application can continue to run on .Net 9 whereas garnet can still run on .Net 8.
