Update dependency xmldom

[karfau]

Switching from package xmldom to @xmldom/xmldom, which resolves the security issue present in latest xmldom version 0.6.0:
GHSA-5fg8-2547-mr8q

The reason is that the maintainers were forced to switch to a scoped package since 0.7.0:
xmldom/xmldom#271

• I only changed all occurences of xmldom, I didn't execute npm install or any other scripts.
• Since there is no package-lock.json, I have no idea what version of xmldom people were actually using (depends on the time of running npm install), so I'm just assuming everybody was using 0.6.0
• fixes Please move from xmldom to @xmldom/xmldom #41

I'm one of the xmldom maintainers. Don't hesitate to ask me questions about it.

Changes in xmldom since 0.6.0

## [0.8.0](https://github.com/xmldom/xmldom/compare/0.7.5...0.8.0)

Fixed

• Normalize all line endings according to XML specs 1.0 and 1.1
  BREAKING CHANGE: Certain combination of line break characters are normalized to a single \n before parsing takes place and will no longer be preserved.
  • #303 / #307
  • #49, #97, #324 / #314
• XMLSerializer: Preserve whitespace character references #284 / #310
  BREAKING CHANGE: If you relied on the not spec compliant preservation of literal \t, \n or \r in attribute values.
  To preserve those you will have to create XML that instead contains the correct numerical (or hexadecimal) equivalent (e.g. 	, 
, 
).
• Drop deprecated exports DOMImplementation and XMLSerializer from lib/dom-parser.js #53 / #309
  BREAKING CHANGE: Use the one provided by the main package export.
• dom: Remove all links as part of removeChild #343 / #355

Chore

• ci: Restore latest tested node version to 16.x #325
• ci: Split test and lint steps into jobs #111 / #304
• Pinned and updated devDependencies

Thanks so much for taking care, and apologies for the delay. I'm not able to keep up with github notifications. I should probably update this library to 2022 and add a package lock, though I am not using this library actively so I haven't gotten around to it.
