fix: config of ignored contexts and patterns (#1901)

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.
