Readme Build status is not working anymore

Hello,

In the Readme.md, the link for the build status is pointing to build.svg but look like we should use pipeline.svg now. Due to that, the image is not displayed.

I think you should change

[![build status](https://gitlab.com/fdroid/fdroidclient/badges/master/build.svg)](https://gitlab.com/fdroid/fdroidclient/builds)

to

[![build status](https://gitlab.com/fdroid/fdroidclient/badges/master/pipeline.svg?key_text=build)](https://gitlab.com/fdroid/fdroidclient/-/pipelines)

or something similar.

By the way, in the project description, there is 2 times the pipeline badge...

Best regards, GK
