Chrome v132 no longer supports old headless mode

For now, to avoid disruption, chromote defaults to using the old headless mode. In the future, chromote will follow Chrome and default to `"new"` headless mode. (And at some point, Chrome intends to remove the old headless mode which is now offered as [a separate binary](https://developer.chrome.com/blog/chrome-headless-shell).) To test the new headless mode, use `options(chromote.headless = "new")` or `CHROMOTE_HEADLESS="new"` (in `.Renviron` or via `Sys.setenv()`). (#172)

It seems the hour is upon us:

Error in `with_random_port()` at chromote/R/chrome.R:195:3:
! Cannot find an available port. Please try again.
Caused by error in `startup()`:
! Failed to start chrome. Error:
Old Headless mode has been removed from the Chrome binary. Please use the new Headless mode (https://developer.chrome.com/docs/chromium/new-headless) or the chrome-headless-shell which is a standalone implementation of the old Headless mode (https://developer.chrome.com/blog/chrome-headless-shell).

Removed in Chrome 132+: https://developer.chrome.com/blog/removing-headless-old-from-chrome

Note that with chromote 0.3.1, you can opt into using the new headless mode by setting

options(chromote.headless = "new")

or via the env var

CHROMOTE_HEADLESS=new

[chlebowa]

Yes, that's what I did. Thank you for including that in the NEWS 👍

This issue has been resolved in the dev version of chromote. Please try upgrading chromote or using the chromote.headless option listed above. If you are having trouble with Chrome or chromote after trying the above, please open a new issue with a small, reproducible example. Thanks!
