Bug: Tags Duplicated when Whitespace around Tag in YAML

Describe the Bug

When there is a tag in the file and the front also has a tag, duplicate tags are generated and there are problems with the YAML format.

How to Reproduce

Question 1:

1. My Linter settings:

2. I did the following first:

   1. I had some tags in YAML, moc and roadmap
   2. Then I added test1 test2 test3 to the article, which at the moment is formatted using linter and everything works perfectly

3. Then I add tags #todo and #doing to the end of the YAML, using the symbol # for smart hints. The file’s tags are like this,

4. Then use Linter to format the file,

   • todo' is missing ,`
   • with an extra test3 at the end

Question 2:

Must have tags in YAML and tag # in the article content.

1. If tags end with a space(bcd ]) or start with a space([ abc), like:

   ---
   tags: [ abc, bcd]
   ---
   
   # h111111
   
   #bcd
   
   * 11111
   * 2222 #abc
   

2. The latest tag will add again.

Expected Behavior

Should probably be added without duplicating the tag and have the correct formatting.

tags: [moc, roadmap, test1, test2, test3, todo, doing]

There may be a future based on this issue. Can the corresponding tag in YAML be automatically deleted when the tag is deleted from the article content?

Maybe it could be implemented like this linter-yaml-title-alias function.

This would have to be another FR since it is a bit different. The only problem is this gets really tricky if you have tags that are not in the YAML front matter that you want to keep.

This issue should be resolved on master and the next release. Please let us know if this is not resolved on either master or the next release (I plan to release the bug fixes today or tomorrow). Feel free to put in the feature request for the keeping of tags in sync with the body content.
