chore: prepare v0.50.3

[julienrbrt]

Description

do not merge yet

It's time for our monthly patch release.
Prepares v0.50.3: v0.50.2...release/v0.50.x
Waiting for #19007 and #18991

Before this, I'll make ready a new version of log and maybe depinject (so people can already use the new appmodule package if they want to for limiting api break when going to v0.51 and new core) from main.
On release/v0.50.x @tac0turtle should we do store as well?
