chartjs-chart-financial example doesn't work with chart.js version 3.8.0 and above

[Arantiryo]

Expected behavior

chartjs-chart-financial example should work with the latest Chart.js version.

Current behavior

The following error message is displayed:

Optional extra steps/info to reproduce

No response

Possible solution

Looks like isPatternOrGradient helper function has been changed in v3.8.0 as the example works just fine with v3.7.1.
Error is thrown when a Proxy object is passed to isPatternOrGradient so updating isPatternOrGradient to handle this use case should solve the issue.

This issue should probably be moved to https://github.com/chartjs/chartjs-chart-financial/issues
