Update DAVx5 in AuthToken.vue

[rfc2822]

Hi,

Please have a look at these changes:

1. It's named DAVx5 (only very old clients have DAVdroid in the User-Agent)
2. Use passive matching (?:droid|x5) because otherwise, "x5" is recognized and shown as operating system
3. Also include the version postfix which contains information like "-beta2", which is important for the user

Is renaming the constant davDroid to davx5 somehow problematic?

[rfc2822]

This is how DAVx5 is shown before the MR:

1. "DAVx5" is shown as "DAVdroid"
2. "-beta2" is missing next to "3.3.8"
3. "x5" is shown as operating system

Do you need any other information to review the changes?

Sounds good!

I'm also fine if we leave the old user agent in for any older clients? Or is that too unlikely that someone still uses the davDroid app?

[rfc2822]

Yes I'd keep the (?:droid|x5) (as I have done in the MR) which should match both ones, just to be sure. I think they should both be displayed as DAVx5, which is the official name since 1.1.2019.
