Update CLI version metadata of every v7 sample script

[milanholemans]

In v7 of CLI for Microsoft 365, we introduced the --force flag instead of --confirm. All sample scripts were updated to use --force, but we forgot to update the metadata file to the correct version.

E.g., for this sample script, the version should be updated to 7.0.0.

cli-microsoft365/docs/docs/sample-scripts/spo/delete-site-scripts/assets/sample.json

Lines 20 to 25 in 515b009

	"metadata": [
	{
	"key": "CLI-FOR-MICROSOFT365",
	"value": "6.3.0"
	}
	],

Let's get this fixed for all sample scripts using --force.
