Maintenance update to support the latest PlatformIO, with a minor fix for SKR 1.3 pins.

• 🩹 Add missing FORCE_SOFT_SPI (#24940)
• 🧑‍💻 Update Python indentation
• 🔨 Support for latest PlatformIO

Known Issues

Marlin 2.1.2

Marlin 2.1.2 introduces Input Shaping to compensate for machine vibrations by carefully timing its movement impulses. Input Shaping results in much cleaner output and allows for higher print speeds with no loss of quality. Although this implementation has received extensive testing, it is still considered experimental. Please report any issues. Use a test print that applies a range of frequencies to find the best settings for your machine. (See M593 Input Shaping)

Marlin 2.1.2 contains many fixes and improvements, and is recommended for all users of Marlin.
