What went wrong

When editing json files using jq for linting, ALE doesn't report the errors correctly.

1. Enabled jq for in g:ale_linters for json
2. Edited a json file with errors

As you can see the details below, jq returns jq: parse error: Expected separator between values at line L, column C for each error. But, in file ale_linters/json/jq.vim(line 8), the regexp to catch the errors/warning is let s:pattern = '^parse error: \(.\+\) at line \(\d\+\), column \(\d\+\)$' (note the ^ in the regexp). Therefore, jq's output is not properly parsed.

using let s:pattern = 'parse error: \(.\+\) at line \(\d\+\), column \(\d\+\)$' (without ^ in the regexp) gives me expected results, but I'm not sure whether it is correct way to fix it.
