Bundle and extension versions should be logged to app insights when using default log level

A customer should be able to check their logs in app insights to see what version of their bundle and/or extensions are being used, without having to tweak logging levels. I tested with a v3 python app using the default host.json settings:

```json
{
"version": "2.0",
"logging": {
"applicationInsights": {
"samplingSettings": {
"isEnabled": true,
"excludedTypes": "Request"
}
}
},
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[2.*, 3.0.0)"
}
}
```

The only log entries I see in the traces table that refer to extensions or bundles is a message about a warmup extension.

I believe this information was logged in the past, and it may have been regressed by some logging verbosity changes.

Reproduce with a v3 Python app using the default host.json settings shown, then inspect Application Insights traces for extension-bundle and extension version messages. Compare the current output with the reported prior behavior; done means those versions appear at the default log level without changing logging settings.
