Dependency changes for v9 tracking issue

[martinothamar]

Description

We need to cleanup package dependencies for v9

• chore(deps): update dependency altinn.apiclients.maskinporten to v9 (main) #507 was closed due to breaking change, will will replace this dependency with the ongoing work for automating Maskinporten integration
• chore(deps): update dependency jwtcookieauthentication to v4 (main) #510 was closed due to KeyVaultSettings being removed. It is used by apps due to our SecretsClient and custom configuration of KeyVaultClient (both directly and transitively) from a deprecated package
• chore(deps): update dependency altinn.common.accesstokenclient to v3 (main) #539 was closed due to a deprecated package being used (through transitive dependency) in SecretsClient

The last two should be resolved/refactored together by providing a SecretsClient abstraction that works better and hides the implementation details. It should use the newser Azure SDKs including Azure.Identity.

Other dependencies which are deprecated and/or contain vulnerabilities need to be dealth with.
