Fix install button selector for Falcon UI change (#115)

* Update pylintrc py-version from 3.9 to 3.13

The Foundry Python runtime is 3.13. Update pylint target to match
so linting validates against the correct language features.

* Fix install button selector: 'Install app' renamed to 'Save and install'

The Falcon App Catalog UI renamed the install button from 'Install app'
to 'Save and install'. Update the selector to match, with .or() fallback
for backwards compatibility.
