Problem: The Tools dropdown is incomplete and however contains two links, "Exploring Linked Data" (https://github.com/wikimedia/wikidata-query-rdf/blob/master/docs/exploring-linked-data.md) and "SPARQL Rest Endpoint" (https://www.mediawiki.org/wiki/Wikidata_query_service/User_Manual#SPARQL_endpoint), that actually should appear on the Help dropdown. Both dropdowns have some inconsistencies.

Acceptance criteria:

• The Tools dropdown now shows the label "More tools", "Other tools" or similar, clarifying that it provides links to tools different from the Wikidata Query Service.
• The label is a button linking https://www.wikidata.org/wiki/Wikidata:Tools.
• The dropdown offers direct links to each tool category on https://www.wikidata.org/wiki/Wikidata:Tools.
• The dropdown offers an additional link to https://tools.wmflabs.org/hay/directory/#/search/wikidata.
• There are no icons next to the links for consistency reasons.
