Bump cm-promql to v0.15.0

[Nexucis]

• upgrade codemirror-promql to v0.15.0
• inject the metricNames in the PromQLExtension
• update the import paths accordingly to the changes provided by this new release.
• I also took the opportunity to move the @types packages from the dependencies list to the dev-dependencies. I hope you don't mind that I did it.
  the @types/ packages are only used for the development, and not used to run the webapp. So these should move to the dev-dependencies part.

This PR synchronizes the changes performed on Prometheus side through the PRs prometheus/prometheus#8706 and prometheus/prometheus#8719

Thank you so much for this work. We really appreciate this work 🤗

At one point... would like to help us maintaining Thanos on UI side?

Oh cool thanks @bwplotka.

At one point... would like to help us maintaining Thanos on UI side?

Maybe it could be nice at some point, but maybe before saying a definitive yes, it would be nice to know what is the expectations and what does it mean to do that :D.
