Update pyroscope/ebpf to v0.4.6 (#678) (#6917)
Browse files Browse the repository at this point in the history 
* Update pyroscope/ebpf to v0.4.4

Note: Pyroscope updated its prometheus/common dependecy and hence this
required further updates.

* Also update windows exporter

* Allow pid maps to be configured

This also modifieds the way we do defaulting and valides those two new
fields.

* Update pyroscope/ebpf v0.4.5

This updates the pyroscope/ebpf annotations to both have alloy and
river ones.

* Add some testing for argument validation

* Update to v0.4.6 to fix debug data

This also includes a test to make sure debug data is marshalled
correctly.
