We run our CI (Continuous Integration) build for our app using GitHub actions and part of that is to install and run the Salesforce CLI Scanner. We run on ubuntu-latest that is documented to have "7 GB of RAM memory".
But starting late yesterday, the install sfdx plugins:install @salesforce/sfdx-scanner is failing with this JavaScript out of memory error:

Any insight or advice on how to fix appreciated.
PS
Adding this export NODE_OPTIONS=--max_old_space_size=4096 to give Node more memory didn't help.
