beam 3189 - initial net7 support

[cdhanna]

Ticket

https://disruptorbeam.atlassian.net/browse/BEAM-3189

Brief Description

Upgrading all the "net6" to "net7" and also taking this opportunity to upgrade a few of our internal dependencies to their latest versions.

Not sure if we should totally send this yet, because it seems like net7 has a regression regarding cross cpu compilation in docker.
