feat: [WD-32154] Anonymise domain name

[Kxiru]

Done

• Anonymises hostnames in stack traces using regex.

Outstanding questions:

• The regex targets urls that begin with 'https://' and have '/ui/' after the host portion. Does the https syntax have any limitations, or is it always expected LXD will run on a https web?
• I must generate a real error to test the stack trace.

Related to: #1670

QA

1. Run the LXD-UI:
   • On the demo server via the link posted by @webteam-app below. This is only available for PRs created by collaborators of the repo. Ask @Kxiru or @edlerd for access.
   • With a local copy of this branch, build and run as described in the docs.
2. Perform the following QA steps:
   • Create an error in the UI (Or not) and select "Report a bug" in the navigation bar.
   • Ensure in the generated Github issue, that the hostname has been replaced with the <ANONYMOUS_HOST> placeholder.
