Add suppression for Performance warning for fetching of misfit data in storage_info_widget

[SAKavli]

Issue
Resolves #12773

I tested this on TGX to double check that the warnings disappeared.
We discussed that this might not warrant a test, especially because the endpoint in "LibresFacade" is to be deprecated at some point.

Approach
Short description of the approach

(Screenshot of new behavior in GUI if applicable)

• 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 'just rapid-tests')

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: Add backport label to latest release (format: 'backport release-branch-name')
