DOCS-2949: Fix mismapped methods

[JessamyT]

• Fixes mixup of value vs name, ex. AnalogByName != analogReaderValue, same issue with interrupt.
• The actual proto names for "Write," "Read," and "Value" are WriteAnalog, ReadAnalogReader and GetDigitalInterruptValue, and using those consistently may help avoid the above confusion ^ in the future
• Don't merge until https://viaminc.slack.com/archives/C0653ULNNAX/p1730506244310229 is resolved
• Move GetGeometries further down the page because it's not board-specific and thus belongs at the bottom near the other inherited methods
