docs: point the issue chooser at the platform adapter vote

[DavidCozens]

Purpose

The four platform-adapter epics — wolfSSL (#691), lwIP Sockets (#692),
LittleFS (#693) and Zephyr (#694) — are deliberately left unmilestoned, so a
thumbs-up on one carries real signal about demand rather than being a reaction
to something already committed. Nothing in the repository told a reader that,
or where to go and do it.

Found as an uncommitted working-tree change with no branch behind it, predating
the TLS rework. It is unrelated to that work and is raised on its own so it
neither waits several weeks nor gets swept into an unrelated commit.

Change Description

One contact link added to the issue chooser, pointing at the open issues
carrying the platform label, sorted by reactions. The sort matters: the list
arrives already ordered by demand, so the most-wanted adapter is the first thing
a reader sees, and adding a vote is one click from there.

Placed below the two security routes and above commercial licensing. The free
way to influence what gets built should come before the paid one.

Test Evidence

No code, so no unit tests. Verified by hand:

• The platform label exists.
• The link's query returns exactly the four platform epics — E34: wolfSSL platform support #691, E35: lwIP Sockets API platform support #692, E36: LittleFS platform support #693,
  E37: Zephyr platform support #694 — and nothing else, so it cannot present committed work as open to a
  vote.
• The file parses as YAML and yields three contact links.

Areas Affected

.github/ISSUE_TEMPLATE/config.yml alone. No library code, no documentation
build, no derived projects. blank_issues_enabled is unchanged, so the existing
templates and the two security routes behave exactly as before.
