community-usermods: add Sensors I2C

[AustinSaintAubin]

Adds an index row for a community out-of-tree usermod: Sensors I2C.

It supports the common 3-in-1 I²C environmental breakout — HTU21D (temp/humidity), BMP180 (temp/pressure), BH1750FVI (lux) — reports to the Info page / /json and optional MQTT/Home Assistant, and can drive WLED's overall brightness from ambient light.

• Repo is public, tagged with the wled-usermod topic, MIT licensed, release v1.0.0.
• Self-contained (no wled00/ changes); consumed via the git-URL custom_usermods mechanism. Verified building into WLED for ESP32.

Single-line addition to the community usermods table, following the documented format.

Summary by CodeRabbit

• Documentation
  • Added a new Community Usermod entry for Sensors I2C on esp32.
  • The listing includes supported I²C environmental sensors, licensing details, and notes about auto-brightness plus optional MQTT/Home Assistant integration.

Poem

🐇 A new sensor row hops into the table today,

BMP180 joins the WLED brigade,
Brightness auto-tuned, MQTT relayed.
The docs grow longer, one small line at a time! 🌡️

LGTM! The new table row follows the existing format and accurately reflects the usermod's capabilities as described in the PR objectives.

Optional: Consider expanding MQTT/HA to MQTT/Home Assistant for readers less familiar with the abbreviation, aligning with the guideline to avoid unexplained jargon.

In `@docs/advanced/community-usermods.md` at line 33, The new community-usermods
table row is fine, but the “MQTT/HA” abbreviation may be unclear to some
readers. Update the Sensors I2C row in the community-usermods table to spell
this out as MQTT/Home Assistant while keeping the rest of the row format
unchanged.
