Subject: [PATCH] Regex string threaded literally instead as regex

During shellcheck of Hestia source code I noticed the following error matching the line:
^----^ SC2076: Don't quote right-hand side of =~, it'll match literally rather than as a regex.
                                                                                      ^--------------^ SC2076: Don't quote right-hand side of =~, it'll match literally rather
Proof of concept:
root@dev:~# v-add-web-domain jaap jaap..nu
Error: nginx restart failed
root@dev:~# v-add-web-domain jaap jaap..nu
Error: invalid domain format :: jaap..nu
