E0051: octal number literal has no digits

Octal number literals start with 0o and require at least one digit. It is an error to write 0o with no following digits:

let mask = 0o

To fix this error, write digits after 0o:

let mask = 0o700;

Alternatively, remove o to create a 0 number literal.

Introduced in quick-lint-js version 0.2.0.
