tmp_path_retention_count config value type incorrect

[AJDurant]

I'm using pytest 9.0.2 and Python 3.13.5 (from uv) on Ubuntu 22.04

In my pyproject.toml I'm using the new pytest options (not ini_options), but for the setting tmp_path_retention_count if I set it to an int value (as in the schema) I get the following error:

pyproject.toml: config option 'tmp_path_retention_count' expects a string, got int: 1

If I set it as a string the schema validation fails as it expects me to be using ini_options

pyproject.toml settings:

[tool.pytest]
cache_dir = ".cache/pytest"
junit_logging = "system-out"
junit_log_passing_tests = false
# Only keep one set of test output, and only if failed
tmp_path_retention_count = 1
tmp_path_retention_policy = "failed"

[AJDurant]

seems to be deliberate from #13904 / #13958 but the schema my editor picks up https://www.schemastore.org/partial-pytest.json still wants an int

[The-Compiler]

That seems like a bug with schemastore rather than pytest.
