Serve PR decoration images as static resources

[don-vip]

Describe the bug
In order to display the PR decoration icons in the notifications created by the plugin, it is currently necessary to either have Internet access to https://raw.githubusercontent.com/mc1arke/sonarqube-community-branch-plugin/master/src/main/resources/pr-decoration-images or to host the images on a private web server and configure the com.github.mc1arke.sonarqube.plugin.branch.image-url-base property.

Expected behavior
All of this should not be necessary. SonarQube allows plugin to serve static resources as follows:

If you need to serve static resources from your plugin such as images or JavaScript files, place them in a directory under resources named static (myplugin/src/main/resources/static). At runtime they'll be available from http://{server}/static/{pluginKey}/{file}.

Software Versions

• SonarQube Version: 8.0
• Plugin Version: 1.2.1-SNAPSHOT (current master)

As per above request , we no longer need to download file from https://raw.githubusercontent.com/mc1arke/sonarqube-community-branch-plugin/master/src/main/resources/static for sonar which is not accessible from github.
Then what configuration si required for PR decoration, do I need to update Images base URL property in General > Pull Request settings ? If yes what needs to be updated in that
