Bump plotly.js to 2.25.2

Fixes #2463

@cpsievert this seems to work at first glance as a drop-in replacement to the JS version, based on spot-checking a few plots and running the test suite.

I had trouble getting the visual tests to work, so those are the ones skipped in this test count.

I was getting the 22 warnings prior to making the JS version update, so those are not new here.

Feel free to adjust the R version and notes for it, or handle that separately. Thanks!

We encountered similar issue in our system and posit is blocking the installation of plotly due to plotly.js CVE. Is there any ETA on this release ? Thanks !

I plan on taking a look next week. There's a good chance updating will cause seom subtle and easy-to-miss regressions, so it's gonna require a careful look from me.

Thanks @bhogan-mitre, I'll take things from here (see #2471)
