Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

@chaozwn do you know : https://github.com/kozer/emmet-language-server
I tested it, and it's better than emmet-ls

kozer/emmet-language-server seems unmaintained

sorry, it's https://github.com/olrtg/emmet-language-server

It's very new, so I think we should stay away from it for now. Perhaps we'll move to it in the future.

emmet_language_server can not transform m5 to margin: 5px,.Their functionalities are almost identical, unless there are obvious bugs. Currently, I don't feel that this new Emmet LSP has any essential features that require switching.
