More improvements for the crate publishing pipeline (paritytech#13153)

* more improvements for the crate publishing pipeline

* move default definitions to the publish-crates script

* add script to check the crate publishing pipeline at the start

* fix yaml references

* move more variables to .crates-publishing-pipeline

* separate .crates-publishing-pipeline from .crates-publishing-variables

* clean up redundant and unused code
