chore(deps): bump plotly from 6.8.0 to 6.9.0

[dependabot]

Bumps plotly from 6.8.0 to 6.9.0.

Release notes

Sourced from plotly's releases.

v6.9.0

Fixed

• Raise a clear ValueError when an unsupported marginal plot type is passed to Plotly Express, instead of failing later with a cryptic 'NoneType' object has no attribute 'constructor' message [#5625], with thanks to @​eugen-goebel for the contribution!

Updated

• Update plotly.js from version 3.6.0 to version 3.7.0. See the plotly.js release notes for more information [#5639]. Notable changes include:
  • Rename sendDataToCloud modebar button to sendChartToCloud, and update to upload chart to Plotly Cloud [#7802, #7852, #7854]. NOTE: The Plotly Cloud endpoint for receiving charts is not yet functional, so this button won't complete the upload.
  • Fix stale scattergl error bars after toggling traces with mixed error bar visibility [#7773], with thanks to @​JulienIcon for the contribution!
  • Fix geo fitbounds to choose a compact longitude range when point data straddles the antimeridian [#7837], with thanks to @​SharadhNaidu for the contribution!

• Read and write figure JSON files as UTF-8 in read_json/write_json so figures containing non-ASCII text are handled correctly on platforms whose default encoding is not UTF-8 (e.g. cp1252 on Windows) [#5633]
