Remove use of deprecated types

[eivindjahren]

List, Dict, DefaultDict, Set, & Tuple are deprecated since python 3.9, but supported without deprecation warning at least until python 3.14. Then there wil least two versions with deprecation warnings before removal so not removed until python 3.16 (2027).

• PR title captures the intent of the changes, and is fitting for release notes.
• Added appropriate release note label
• Commit history is consistent and clean, in line with the contribution guidelines.
• Make sure unit tests pass locally after every commit (git rebase -i main --exec 'pytest tests/ert/unit_tests -n logical -m "not integration_test"')

When applicable

• When there are user facing changes: Updated documentation
• New behavior or changes to existing untested code: Ensured that unit tests are added (See Ground Rules).
• Large PR: Prepare changes in small commits for more convenient review
• Bug fix: Add regression test for the bug
• Bug fix: Create Backport PR to latest release
