Culture problem with webhook token regex validation

[serkanyazicioglu]

Hello,

Webhook url validation regex fails when used with various different cultures. You can basically add 'RegexOptions.CultureInvariant' to WebhookUrlRegex object to mitigate the issue.

private static Regex WebhookUrlRegex = new Regex(@"^.*(discord|discordapp)\.com\/api\/webhooks\/([\d]+)\/([a-z0-9_-]+)$", RegexOptions.CultureInvariant | RegexOptions.Compiled | RegexOptions.IgnoreCase);

Thanks...
