feat(fix): Pinout on M8P V2

[3dprintpt]

Corrections on Manta M8P V2 spi pins

Summary by CodeRabbit

• Chores
  • Reassigned software SPI pins for the BTT Manta M8P 2.0 motherboard (stepper and all eight motors) to improve hardware compatibility and motor reliability.
  • Standardized deployment commit metadata across release processes: publishing now records the GitHub Actions bot as the committer to unify commit attribution.

Walkthrough

Updated BTT Manta M8P-20 board definition to remap software SPI pins for MOTOR1–MOTOR8 and stepperSPI from PC10/PC11/PC12 to PG6/PG7/PG8. Also standardized Git commit identity in three CI workflow files to use github-actions[bot] and its noreply email.

Changes

Cohort / File(s)	Summary
Board Configuration configuration/boards/btt-manta-m8p-20/board-definition.json	Remapped software SPI pins for MOTOR1–MOTOR8 from PC12/PC11/PC10 → PG6/PG7/PG8; updated stepperSPI sclk/mosi/miso from PC10/PC12/PC11 → PG8/PG6/PG7.
CI Workflows .github/workflows/publish-development.yml, .github/workflows/publish-devpub.yml, .github/workflows/publish-v2.1.x.yml	Replaced conditional or user-specific git configuration with a fixed deployment identity: git-config-name set to github-actions[bot] and git-config-email set to the bot noreply address (41898282+github-actions[bot]@users.noreply.github.com).

Poem

🐇 I nibbled wires in morning light,

Swapped PC paths for PG bright,
Eight small motors dance in tune,
Commits now signed by a bot moon,
Hooray — a hop, then off I swoon.

Update ADXL345SPI to use the correct SPI3A pins for the M8P V2.0.

The current ADXL345SPI configuration uses PC10/PC11/PC12 with CS on PB12, which corresponds to SPI3, not the correct SPI3A bus. According to the official Klipper reference configuration for the M8P V2.0, ADXL345 should use:

• sclk: PG8
• mosi: PG6
• miso: PG7
• cs_pin: PA15

Updated ADXL345SPI configuration

"ADXL345SPI": {
  "cs_pin": "PA15",
  "software": {
    "sclk": "PG8",
    "mosi": "PG6",
    "miso": "PG7"
  }
}
