Upgrade dependency "archiver" to 7.x

[MennoTammens]

When installing osls, npm gives the following warnings (amongst others):

$ npm install
npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported

Both inflight and glob are dependencies of archiver:

Upgrading archiver to version ^7.0.1 will probably solve these warnings. The only breaking changes in archiver@6.0 and archiver@7.0 are dropping support for old nodejs versions:
