v0.18.0

[metalmatze]

We're happy to release Parca v0.18.0!

This release comes packed with performance improvements, enhancements and so many fixes to the UI and CI!

• Parca will now automatically use the system settings for light or dark themes.
• gRPC Prometheus histograms are now exposed as native histograms giving them a much higher fidelity.
• If running with a custom path prefix, all API endpoints will now be served under this prefix.

Happy profiling!
