* Update worldedit-core/src/main/java/com/sk89q/worldedit/extent/clipboard/io/share/ShareOutputConsumer.java

Co-authored-by: Octavia Togami <octavia.togami@gmail.com>

* Fixed a lot of random comments

* Return a consumer from share rather than a URL, allows the share destination to control output

(cherry picked from commit 6e2b0a1df8a6077c3cf8193e38dc9817038bcbe9)

* chore: cleanup cherry-pick remainders

* chore/feat: add ark as (default) schematic paster / sharing endpoint

* chore: default to fast schematic writer in share

* chore: re-format strings.json (seems to adjusted indentation when merging)

* chore: hopefully fixing strings.json (again)
