incorrect branch name in validate-schema.yml

[ElectricNroff]

The master branch name in

cve-schema/.github/workflows/validate-schema.yml

Lines 4 to 10 in 30f59c7

	branches:
	- master
	pull_request:
	types: [opened, synchronize, reopened]
	workflow_dispatch:
	branches:
	- master

is not compatible with https://github.com/CVEProject/cve-schema/branches

Could you expand on why this should be fixed? Is it causing errors anywhere or just if someone read the branches in the schema and looked for that branch in github?
Also, I assume it should just match the "main" branch name?

GitHub does not have any documentation indicating that a nonexistent branch name is supported in GitHub Actions. It might currently work for our use case, but stop working later. Related documentation suggests that continuing to use an old branch name, after a rename, does not work in some other aspects of GitHub Actions: https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-branches-in-your-repository/renaming-a-branch "GitHub Actions workflows do not follow renames"
