rename GL_TOKEN_READ_REGISTRY to GL_TOKEN_SCANNER_READ_API
https://gitlab.com/gitlab-org/gitlab/-/issues/460398+s
Following this comment
READ_REGISTRY
in the name of this build parameter is misleading.
It is NOT supposed to contain a token with the read_registry
permission.
The purpose of this build parameter is to provide a token with read_api
permission on the scanner project.
For that reason, it will be renamed GL_TOKEN_SCANNER_READ_API
