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 (the name of the language should be the name of the language which the help text is in).
**Notes:**
