bug fix: allow brush with rangeBars

[davidchateau]

New Pull Request

I believe it's currently not possible to use the 'brush' feature with rangeBars charts. JavaScript raises errors because the code attempts to read fields from null objects (e.g., w.globals.xAxisScale).
I have attempted to implement a clean and minimal fix, closely resembling the existing code. Each change is wrapped within an 'if (w.globals.isRangeBar)' condition to avoid interference with other features.

Fixes
I didn't file an issue, but someone raised the problem earlier this year: https://stackoverflow.com/questions/75618138/a-combination-of-two-rangebar-charts-in-apexcharts-but-brush-chart-does-not-work
