feat: allow files rm --force

[SgtPooki]

Is your feature request related to a problem? Please describe.
It's possible for users to get into a state where they have non-unixfs files in MFS, which will result in errors like Error: unrecognized node type in cache node.

When non-unixfs files are in MFS, removal of those files will fail in webui without error.

They also fail to be removed in the command line unless rm --force is used.

Describe the solution you'd like
When a user attempts to remove a file, we should provide an option to "force" remove the file.

Describe alternatives you've considered

We may also want to enable a fallback prompt to "force" remove files when a user attempts to remove a file and it fails.

Additional context

We should also prevent users from adding/importing non-unixfs files via the webui (I believe I added the files that got me into this state via the webui)

Code that needs updated

• ipfs-webui/src/files/modals/add-by-path-modal/AddByPathModal.js

  Lines 25 to 31 in 5abc5d0

  	validatePath = (p) => {
  	if (!p.startsWith('/ipfs/')) {
  	p = `/ipfs/${p}`
  	}
  	return isIPFS.ipfsPath(p)
  	}
