az containerapp up parameter env-vars does not consume the value of APPLICATION_INSIGHTS_CONNECTION_STRING

### Describe the bug

az containerapp up --env-vars does not work with APPLICATION_INSIGHTS_CONNECTION_STRING (or any other var that contains "=" regardless of escaping)

Command in question: `az containerapp up`
Parameter: `--env-vars`

Example command:
```
az containerapp up \
--resource-group $(ARM_RESOURCE_GROUP) \
--location $(LOCATION) \
--name $(APPLICATION_NAME)$(SDLC_ENVIRONMENT) \
--ingress external \
--target-port $(PORT) \
--env-vars "AZURE_OPENAI_ENDPOINT=aaaa AZURE_OPENAI_KEY=aaaa ARM_SUBSCRIPTION_ID=fb4dd9d3-f90f-411b-aa7f-beb1ae2b892d LOCATION=eastus2 APPLICATIONINSIGHTS_CONNECTION_STRING=InstrumentationKey=00000000-0000-0000-0000-000000000000;IngestionEndpoint=https://eastus2-3.in.applicationinsights.azure.com/;LiveEndpoint=https://eastus2.livediagnostics.monitor.azure.com/;ApplicationId=00000000-0000-0000-0000-000000000000" \
--logs-workspace-id $(LOG_WORKSPACE_ID) \
--logs-workspace-key $(LOG_WORKSPACE_KEY) \
--workload-profile-name "Consumption" \
--source .
```

Approach 1: Wrap the value of "env-vars" in double quotes
- This results in 1 environment variable on the container app, with all vars in 1 value.

Approach 2: Wrap just the value of APPLICATION_INSIGHTS_CONNECTION_STRING in double quotes:
- This results in an invalid CLI command (some of the parameters are missing)

--logs-workspace-id $(LOG_WORKSPACE_ID) \
--logs-workspace-key $(LOG_WORKSPACE_KEY) \
--workload-profile-name "Consumption" \
--source .
```

### Errors

Approach 1: Wrap the value of "env-vars" in double quotes
- This results in 1 environment variable on the container app, with all vars in 1 value.

Approach 2: Wrap just the value of APPLICATION_INSIGHTS_CONNECTION_STRING in double quotes:
- This results in an invalid CLI command (some of the parameters are missing)

--target-port 3100 \

--logs-workspace-id SomeId \
--logs-workspace-key SomeKey \
--workload-profile-name "Consumption" \
--source . \
--debug
You must specify either --source, --repo, or --image
/bin/sh: 8: --logs-workspace-id: not found
```

### Expected behavior

The parameter `--env-vars` should handle environment variable values with "=" in them.
