Jest plugin doesn't resolve the "rootPath" correctly

[rdrezner]

Hello, thanks for creating and maintaining knip - I really like this tool.

When I scan my project, I'm getting some false positives and they're coming from the jest configuration. Files such as:
<rootDir>/some_file.ts are listed as unused. I have the rootDir property set to ./src in jest config file.

I took a closer look at the jest plugin configuration and I noticed that in this line https://github.com/webpro/knip/blob/59d437d7184bbe5374da00be60ea25993eb63c72/src/plugins/jest/index.ts#L90 the plugin replaces the <rootDir>/ string with the empty one. It seems to me that this is not correct for projects that have the rootDir property defined in the jest configuration (see: https://jestjs.io/docs/configuration#rootdir-string).

When I change this code line to:

const replaceRootDir = (name: string) =>
    name.includes('<rootDir>') ? join(cwd, name.replace(/^.*<rootDir>/, config.rootDir ?? '')) : name;

knip doesn't list those file as unused which is the expected behaviour.
