build: add poetry-plugin-export to the dependencies

Since Poetry 2.0.0, the `export` command has been removed and it's
advised to use the "poetry-plugin-export" package instead.

This commit adds this dependency to the different places it's needed
(debian environments, CI, build instructions, etc).
