Updating Constants.js

[guittari]

Copying my comment from issue aplbrain/BBQS-EMBER-web#18: The new Documentation tab in emberarchive.org, should be reflected in both emberarchive.org, and the reference would be replaced in

dandi-archive/web/src/utils/constants.ts

Line 5 in 6a4820a

const dandiDocumentationUrl = 'https://docs.dandiarchive.org/10_using_dandi/';

, so we would also have a second Documentation tab (that now leads to EMBER flavored instructions) on dandi.emberarchive.org, with the intention to long term replace the second Documentation tab with the finalized/revised PR: aplbrain/dandi-docs#4
