Changed tag for imported content to be internal (#15934)

refs: 8ed5f9784d

- When importing content from a JSON file in Settings > Labs, a public tag
like `Import 2022-12-03 19:57` gets added to each newly imported post.
- This tag should not be public. It definitely serves a useful
purpose but has no useful function for readers of the site and should
not be shown to readers.
