Updated

• Updated Plotly.js to from version 2.17.1 to version 2.18.0. See the plotly.js CHANGELOG for more information. Notable changes include:
  • Add sync tickmode option [#6356, #6443], with thanks to @filipesantiagoAM and @VictorBezak for the contribution!
• Build process now uses Node 18.x and version 2 lockfile (should be an invisible change for users) [#4034]

Fixed

• write_html() now explicitly encodes output as UTF-8 because Plotly.js' bundle contains such characters [#4021] and [#4022]
• fixed iframe renderer regression from 5.12 and also fixed error when this renderer was used in the very first cell in a notebook [#4036]
