can not disable release sync with --github false

[magicdawn]

Environment

node v20.13.0

Reproduction

see below

Describe the bug

usage

1. pnpm changelogen --clean --github false --release --minor
2. git push --tags

with sync release, later tag push will report tag already exists
(and I need to test before push, so I don't want --push)

so I need to disable sync release. I found the code here
https://github.com/unjs/changelogen/blob/v0.5.5/src/commands/default.ts#L141

but this still not working because mri(argv) will treat --github=false / --github false as string, argv.github === 'false'
