<!-- In the case this PR will resolve an issue, please replace
${GITHUB_ISSUE_ID} below with the actual Github issue id. -->
<!-- Closes #${GITHUB_ISSUE_ID} -->

# Rationale for this change
`make test` fails locally since `Config().get_known_catalogs()` also
reads my local `~/.pyiceberg.yaml`

Follow up to #2088

# Are these changes tested?

# Are there any user-facing changes?

<!-- In the case of user-facing changes, please add the changelog label.
