Extension sometimes doesn't start `failed: fetch failed.`

**Describe the bug**
Every now and then when reloading VSCode I will get this error:
`Activating extension 'github.vscode-github-actions' failed: fetch failed.`
```rust
Failed to load resource: net::ERR_NAME_NOT_RESOLVED
marketplace.visualstudio.com/_apis/public/gallery/extensionquery:1

ERR [network] #5: https://marketplace.visualstudio.com/_apis/public/gallery/extensionquery - error POST Failed to fetch
log.ts:439
```

**To Reproduce**
Steps to reproduce the behavior:
1. Reload VSCode with `workbench.action.reloadWindow`
2. Get lucky (unlucky?)
3. See error

**Expected behavior**
Extension starts every time with no problems

**Screenshots**

**Extension Version**
`v0.27.0`

**Additional context**

Start by tracing extension activation and the request to marketplace.visualstudio.com/_apis/public/gallery/extensionquery, then reproduce the failure by reloading VSCode with workbench.action.reloadWindow. Done means the extension activates reliably after reload without the reported fetch failure.
