Webhook creation could show non-clickable version of the link

[DHaussermann]

When you create a webhook via slash command, the address that GitLab uses for the webhook is shown in the confirmation post. This is displayed as a clickable link which may be a bit confusing for people. Even though the link is correct, attempting to follow it will result in a 401 response and the text not authorized .

It may make more sense to show the link as a commented line of text https://dkh-local.ngrok.io/plugins/com.github.manland.mattermost-plugin-gitlab/webhook rather than the clickable link https://dkh-local.ngrok.io/plugins/com.github.manland.mattermost-plugin-gitlab/webhook

Steps:

• Subscribe to a project
• Using the slash command, add a webhook to deliver the evsent

Observed:
A. Confirmation post shows a list of events and a clickable link such as https://dkh-local.ngrok.io/plugins/com.github.manland.mattermost-plugin-gitlab/webhook
B. Clicking the link results in 401
