Update docker base image & respect sonar-project.properties

[jankal]

Description

As the title says, I updated the base image this image relies on so it now ueses SonarScanner v4.5. The image size might be accacted. I think, this is a non-issue bc GitHub handles pulling the image.
I also added logic to detect a sonar-project.properties file in the current directory. When one is present the config settings from that file are used instead of settings from GH Actions or auto-generated settings (like projectName being the repo name).

Fixes #5
Also updates Docker base image to Sonar-Scanner v4.5

Motivation and Context

The upstream docker image already dates back one year. I also hope to get rid of the node:8 warnings in SonarQube.

Hi, @jankal. Is c949545 passed test?

[jankal]

@dwisiswant0 thank you for checking back again. I found issues on line 17 of entrypoint.sh which I have to fix first. Do not merge.

@dwisiswant0 now I think it's all fixed up :)

But it might be a good idea to also test it on other projects first.
