Cross-platform log retrieval UX/UI bug

- OS: macOS Monterey 12.2.1 (21D62)
- Version of IPFS Desktop Version 0.18.1 (0.18.1)
- UI v2.13.0 ([44a46ba](https://github.com/ipfs/ipfs-webui/commit/44a46ba)) 
- go-ipfs version: `ipfs version 0.12.0`

**Describe the bug**

There are no instructions for getting the logs for a macOS IPFS-Desktop user.

**To Reproduce**

In the bug template, users are advised to get logs from the GUI, or via path in linux:

```

```

**Expected behavior**

1. GUI should have menu link to get logs on all platforms
2. Paths to logs should be visible in UI on all platforms.
