Is your feature request related to a problem? Please describe.
Lot of software developers are discussing on twitter to rename default branches for their projects from "master" to "main" or equivalent https://twitter.com/search?q=master%20branch&src=typed_query

The primary reason being master-slave an oppressive metaphor.

Describe the solution you'd like
Node.js core follows the trend to change the industry standard, and renames default branch from "master" to "main" or similar

Describe alternatives you've considered
Sticking with existing master branch name for the default

EDIT: Updated "renaming master to main" to "renaming default branch name from 'master' to 'main'"
