Formatting edits for 2nd edition publication

[gesa]

Aligns formatting of ECMA-424 more closely with the Ecma standard template. The associated PDF was compiled with ecmarkup@6715c1e (tc39/ecmarkup#661)

A complete list of editorial modifications:

• capitalisation on title and all headers
• set status to "standard"‡
• add standard adoption info for upcoming Ecma GA
• modify normative references overview paragraph to default (i believe editors are entitled to drop this modification)
• reorder normative references to put Ecma standards first
• add a local pdf generation npm script (editors may wish to reject this change as well) (please let me know if this script necessarily cannot produce the appropriate content)
• update table 1 caption

‡ I recommend once this is merged that you create a new branch for the opt-out period, and change the metadata on the main branch back to status: draft as well as version: 3<sup>rd</sup> edition

Informative: a possibly-abridged list of ecmarkup changes

• table & figure caption colour and punctuation (specifically in print output)
• terms & definitions rendering
  • each term using untitled clauses and displayed on its own line
  • removal from table of contents
• office address removed from front cover
• render toc 3 levels deep instead of 2
• remove "draft" copyright option
