As an editor I want to create a new schema in order to start defining how a certain part of the data should look like.
**Screenshots/mockups:**
{F27877275}
**BDD**
GIVEN the SpecialPage "Special:NewSchema"
THEN there is an introductory text
AND there are input fields for labels, descriptions and aliases
AND the input fields have inline help text
**Acceptance criteria:**
[] introductory text ("By clicking "Create", you agree to the terms of use, and you irrevocably agree to release your contribution under the Creative Commons CC0 License.") <- same as on https://www.wikidata.org/wiki/Special:NewLexeme
[] input fields for labels, descriptions and aliases including inline help text, as shown in the mock up above.
