docs: replace the single-name contributor table with docs shortcuts and open thanks

The Hardware Contributors table had exactly one entry. With one name it
reads as if nobody else has contributed, and as more are added it becomes
a maintenance burden that quietly excludes whoever was missed.

Replaced with a Thanks section that describes the kind of contribution
that actually moves this project -- scans at two operating points, a
noticed 0.0 C reading, a protocol document obtained from Growatt -- and
points at where credit already lives: the release notes, the originating
issue, and comments beside the registers each report established. That
keeps attribution attached to the thing it explains instead of in a list
that goes stale.

Also adds a Documentation table linking the eight most useful pages. The
site was linked once at the top with no indication of what is on it. All
nine URLs verified 200.

+## Thanks
 
----
+This integration is built almost entirely on evidence from people's own hardware. Register
+maps get confirmed because someone ran a scan at two different times of day; wrong mappings
+get found because someone noticed a battery reading 0.0 °C and said so; whole model
+families get supported because someone asked Growatt for a protocol document and shared it.
 
-## Hardware Contributors
+Several of the most useful reports were people **correcting their own earlier findings**
+after measuring properly — which is what stopped working registers being "fixed" into
+broken ones.
 
-The following community members contributed live hardware testing, field diagnostics, and official protocol documentation that directly shaped this integration:
+Contributions are credited where they're used: in the
+[release notes](https://github.com/0xAHA/Growatt_ModbusTCP/releases), in the issue each one
+came from, and in comments beside the registers they established. That keeps the credit
+attached to the thing it explains, rather than in a list that goes stale and quietly
+excludes whoever was added last.
