Fix change surrounding tag, fixes #8177

[robertmoura]

Big thanks @J-Fields for maintaining this project 😊

What this PR does / why we need it:
Fixes a "change surrounding tag" issue when using kebab case

<custom-tag></custom-tag>

When using a command to replace the tag with h1 you get this:

<h1-tag></custom-h1>

Which issue(s) this PR fixes

• Change tag with symbol does not replace the whole tag #8177

Special notes for your reviewer:
What I've done to try fix the issue is created a new WordType of TagName. Currently it's using nextWordEnd and prevWordStart to select the tag name which is why we are getting that strange behaviour.
