Building the Dockerfile with podman:

$ podman  build -t grafana-dashboard-manager:latest .

Poetry (1.7.1) is installed now. Great!

You can test that everything is set up by executing:

`poetry --version`

[1/2] STEP 6/10: RUN poetry self add poetry-plugin-export
Using version ^1.9.0 for poetry-plugin-export

Updating dependencies
Resolving dependencies...

Because no versions of poetry-plugin-export match >1.9.0,<2.0.0
 and poetry-plugin-export (1.9.0) depends on poetry (>=2.0.0,<3.0.0), poetry-plugin-export (>=1.9.0,<2.0.0) requires poetry (>=2.0.0,<3.0.0).
So, because poetry-instance depends on both poetry (1.7.1) and poetry-plugin-export (^1.9.0), version solving failed.
Error: building at STEP "RUN poetry self add poetry-plugin-export": while running runtime: exit status 1
