New login background as SVG

New login background for v.11 as an SVG.

I kept the old JPG, so it's still there if referenced by some(?)

Notice, this must be cherry-picked for 11.0 branch.

@bergmania Please note that Umbraco 10 only had a custom installer background (see PR #12291), which this PR doesn't replace/update and left the login background to a more generic/muted blue with coloured shapes...

@nielslyngsoe All other static assets are placed within the Umbraco.Web.UI.Client project (and copied as part of the npm build script): what's the reason for adding the new background directly to the static assets RCL?

@ronaldbarendse, the intension is to update the background on each major. Like it changed on minors in the v7 timeperiod.

I think that's great, although I can imagine not everyone will like the updated, colourful background (as it can be a bit distracting from the login panel). Since we still ship the previous, more generic/muted background, they can easily set Umbraco:CMS:Content:LoginBackgroundImage to assets/img/login.jpg and revert back to that one👍🏻

Shouldn't we also change the installer background by changing the following to the new login.svg?

Umbraco-CMS/src/Umbraco.Web.UI.Client/src/less/installer.less

Line 34 in b69afe8

background: url('../img/installer.svg') no-repeat center center fixed;

We can then also remove the installer.svg file (since that's hardcoded into the CSS and most likely not referenced anywhere else) and possibly rename login.svg to a more generic background.svg?

The installer background is fairly new and we do not plan to change that for each version.

And as you say, people can easily change the background image, like before. I always changed the login background to the installer background in v10. Not everyone liked the v8-v10 login background either.
