Publish on JSR with Deno support

[martin-braun]

This package was useful for me on nodeJS. Now I need the same on Deno with the deno.json. I think it would be great if this package would allow me to specify the JSON name after it has been published on JSR.

My current work-around is having this task in deno.json with jq as dependency:

{
    "genversion": "deno eval 'Deno.writeTextFileSync(\"version.ts\", \"export const version=\")' && jq .version deno.json >> version.ts",
}

Without using any path separators, it should be good for Windows, too. Although, the solution is not ideal.
