refactor!: use descriptive strings for reset sequences

[mrazauskas]

Currently \u001b[0m and \u001b[39m sequences are replaced with </> in snapshots. The sequences are different, so I think this should be reflected in snapshots as well. Hence, this PR introduces descriptive strings for all supported reset sequences instead of </>.

For example, <dim><red>some</>text</> becomes <dim><red>some</color>text</> (assuming that first reset is \u001b[39m and second is \u001b[0m).
