Update to 8.2.4

[AnnMarieW]

Added

• attributes prop – Pass custom attributes to inner elements of components that support the Styles API.
• strategy prop for Container – Added strategy="grid" option for grid-based layouts with breakout features.
• target prop for Tooltip – Specify tooltip targets using a selector, HTML element, or ref, as an alternative to children.
• chevronIconSize prop for Accordion – Control the size of the default chevron icon independently from chevronSize.
• keepMounted prop for Collapse – Keep collapsed content in the DOM while hidden.
• autoSelectOnBlur prop for Select and Autocomplete – Automatically select the highlighted option when the input loses focus.

Fixed

• Fixed CSS for CodeHighlight so it works when dcc.Markdown and/or dash-ag-grid are also used in the same app.

Changed

• Upgraded to latest Mantine (8.2.4)

Notes

• The one Select test that's failing is flakey and can be disregarded (the test passes locally).
• no new tests are needed because all the new props are pass-through props only. The docs have examples of each new feature and it all works as expected. See Doc PR #239
• This PR updates to Mantine 8.2.4 (the current version). Will wait for 8.2.5 to fix a bug in autoSelectOnBlur before releaseing DMC 2.2.0. Updating to 8.2.5 can be a separate PR

💃 Looks good, just the version number mismatch changelog vs package.json
