fix: config of ignored contexts and patterns

According to my tests, this fixes Vale checking.
Current vale.ini disables checking in most
of the files, one of the regexes probably being
too greedy. Exctracted from #1890

I couldn't confirm that enabling specific Apify rules like

```ini
Apify.H1 = YES
Apify.Apify = YES
Apify.Capitalization = YES
Apify.Languages = YES
```

is necessary, Vale seems to pick them up correctly on my machine.
