TASK: only show button when enabled

[PRGfx]

This PR creates a new build of the plugin in order to only show the button when the feature is enabled in the node-type configuration.

Changes in this PR

As discussed in #6, this PR updates the build-stack to the current UI-extensibility setup:

• use new @neos-project/neos-ui-extensibility stack with esbuild
• remove dependency on plow-js
• use provided ckeditor-exports rather than installing the @ckeditor
  this resolves a runtime error of having different ckeditor versions
• add lock-file
• restrict package to newer Neos versions

How to verify

• Configure SplitAdd for a single node-type (e.g. Text)

  'Vendor.Package:Content.Text': 
    properties:
      text:
        ui:
          inline:
            editorOptions:
              formatting:
                splitAdd: true

  click into another inline-editable node-type (e.g. a Heading) and into the configured node-type and verify that the Button is in the RTE toolbar only for the node-type with the setting
• Verify that the button still triggers node creation

Open questions

• What can/should we restrict the Neos version to? I only got to test it on 8.2, but I expect that it should work on older versions as well. The relation to the neos-ui-extensibility version is not obvious to me. The ckeditor-exports import might have been breaking at some point...

resolves #6

Ill test this in 7.3 and 8.3 :)

Thanks for the update ;) It looks all good and works as expected. I could also confirm that the option splitAdd was not used previously.

  properties:
    text:
      ui:
        inline:
          editorOptions:
            formatting:
              splitAdd: true

So in the release notes - its still beta so all fine - it should be noted that this option is now always required to be used.

Thank you for updating the tech ;)

I can confirm that this works with Neos 8.3
Well at least how good the plugin ever worked ... i found a few bugs #9
but they are unrelated to this change.

[mhsdesign]

as stated here #8 (review) please mark this change as breaking and add as upgrade note that you have to enable it ;)

  properties:
    text:
      ui:
        inline:
          editorOptions:
            formatting:
              splitAdd: true

(cant edit messages on foreign repos ... dang ^^)

@mhsdesign So you suggest that this is merged and released as a new major version, correct? I would then merge and release.
