Do we still need the local copy of vendor/_rfs.scss?

Context:

• Update NPM packages incl. Hugo to 0.140.2 open-telemetry/opentelemetry.io#5867

When we upgraded to Hugo 0.140.2, I notice the following diff:

diff --git a/scss/main.css.map b/scss/main.css.map

Might there be something that has changed in the way that vendor directories are processed?
