tsp codegen for examples is broken with latest tcgc

[jhendrixMSFT]

For reference Azure/typespec-azure#1688

Also observed was some of the ARM modules have missing/incorrect parameters.

[jhendrixMSFT]

There are at least two issues here.

• the api-version is being added as a parameter to method calls
• some methods are missing parameters

The former is a simple fix.

For the second bullet, an example is in armlargeinstance.

res, err := clientFactory.NewAzureLargeInstanceClient().Update(ctx, "myResourceGroup", "myALInstance", nil)

This method is missing param properties TagsUpdate.

Also impacted is armloadtestservice.

vet.exe: .\zz_loadtests_client_example_test.go:25:105: not enough arguments in call to clientFactory.NewLoadTestsClient().BeginCreateOrUpdate
        have (context.Context, string, string, nil)
        want (context.Context, string, string, armloadtestservice.LoadTestResource, *armloadtestservice.LoadTestsClientBeginCreateOrUpdateOptions)

[jhendrixMSFT]

The api-version issue has been fixed.

confirmed that all the example failure is from setting body parameter name with @encodedName. open tcgc issue here.
