can't re-package (ops pkg multiple times fail)

[next-ramses]

It is not possible to re-package a previously built package, e.g:

ops pkg from-pkg eyberg/java_21.0.4 -c config.json --name mypkg --version 0.0.1

then running again:

ops pkg from-pkg eyberg/java_21.0.4 -c config.json --name mypkg --version 0.0.1

fails with "permission denied", can't delete the previously dir generated at .ops/local_packages/ as the dir is read only.

(also, the doc at https://docs.ops.city/ops/packages is outdated as -n and -v short flags doesn't work, should be --name and --version)

perhaps we should have some sort of --overwrite flag ?
