fix(docz-utils): fix closing tag detection in `removeTags`

[nicolo-ribaudo]

Description

I wrote the description of this fix and the reason behind it at https://github.com/doczjs/docz/issues/1691#issuecomment-1025928444.

I fixed it in different commits:

• test(docz-utils): add test for current removeTags behavior shows the old behavior (one test was correct, the other one was already broken)
• chore(docz-utils): update @babel/* dependencies updates @babel/traverse and the other babel packages, to force the version containing the fix for the bug docz was relying on
• test(docz-utils): update removeTags (broken) snapshots updates the tests to show the new broken behavior
• fix(docz-utils): fix closing tag detection in removeTags fixes both the broken tests

Fixes #1691
