Bug: LogViewer parser regex is greedier than it should be

[aricooperdavis]

The regex used by the Grav\Common\Helpers\LogViewer class to parse lines from the grav.log is too greedy, which means that some log lines are not parsed as expected.

[2023-02-08 05:05:03] grav.DEBUG: [IP Blacklist] Request matched filter '/\.env': 'https://cooper-davis.net/.env' [] []
[2023-02-08 05:05:03] grav.DEBUG: [IP Blacklist] IP blacklisted: '144.48.81.111' [] []
[2023-02-08 05:05:04] grav.DEBUG: [IP Blacklist] IP reported: '144.48.81.111' [] []
[2023-02-08 05:05:04] grav.DEBUG: [IP Blacklist] Request rejected: 'https://cooper-davis.net/.env' [] []

are parsed and displayed in the admin log viewer tool as

This is any easy fix; I'll submit a pull request.
