fix(shared-data): add t20 lld settings to p50 version 3.5

[mjhuff]

Closes RQA-5286

Overview

Whoops, like like we missed adding t20 values to v3.5 for the P50 single channel.

Test Plan and Hands on Testing

Changelog

Tested using the following protocol:

from opentrons import protocol_api
metadata = {
    "protocolName": "20uL tip lld ",
}

requirements = {
    "robotType": "Flex",
    "apiLevel": "2.28"
}

def run(ctx: protocol_api.ProtocolContext):
    ctx.load_waste_chute()

    # --- Hardware & labware setup ---
    # If you hit KeyError: 't20', switch to "opentrons_flex_96_tiprack_50ul".
    tip_rack = ctx.load_labware("opentrons_flex_96_tiprack_20ul", "C1")

    reservoir = ctx.load_labware('nest_12_reservoir_15ml', 'C2')
    plate = ctx.load_labware('corning_96_wellplate_360ul_flat', 'D2')
    
    # MODIFIED: Load P50 Single-Channel Pipette
    pipette = ctx.load_instrument('flex_1channel_50', 'left', tip_racks=[tip_rack])

    # --- Liquid sensing + meniscus aspiration ---
    ctx.comment("Measuring liquid height in reservoir A1, then aspirating at the meniscus...")

    source_well = reservoir["A1"]
    dest_well = plate["A5"]

    liquid_1 = ctx.define_liquid(name="liquid_1", display_color="#000000")
    source_well.load_liquid(liquid_1, volume=10000)

    pipette.pick_up_tip()

    pipette.measure_liquid_height(source_well)
    pipette.aspirate(volume=10, location=source_well.meniscus(z=-1))
    pipette.dispense(volume=10, location=dest_well)

    pipette.drop_tip()

Review requests

• Can we quickly audit and confirm that all other definitions are correct, in particular, should we support 8 Channel P1000s?

Risk assessment

• very low, assuming we want the pipette to support t20s.
