docs(api): Update listed pipette flow rates (#17367)

# Overview

The API docs section on [default pipette flow
rates](https://docs.opentrons.com/v2/pipettes/characteristics.html#pipette-flow-rates)
shows inaccurate flow rates. The parent page/file is
`characteristics.rst`. This updates that table based on the flow rate
data provided in these 2 JIRA issues:

- RTC-667
- RESC-375

Both include a list of default flow rates. 

Excluding 20 uL tips because those are not available yet.

## Test Plan and Hands on Testing

Check the updated table to make sure it reflects the correct default
flow rates.

## Changelog

Change updates and revised the table that lists flow rates for various
pipette and tip combinations.

Minor text changes in section text.

## Review requests

See RTC-667 for a list of flow rates. I think I've got these reproduced
correctly.

## Risk assessment

Low. Docs change only. Minor table and text change in a single section.

 Flex Pipette Flow Rates
 -----------------------
 
-Flex pipette flow rates depend on pipette volume and tip capacity. Each pipette–tip combination has a default flow rate for aspirating, dispensing, and blowing out liquid. When using a 50 µL pipette, you should only use 50 µL tips.

+The following table provides data on the default aspirate, dispense, and blowout flow rates (in µL/s) for Flex pipettes. Default flow rates for each pipette-tip combination are the same across all three actions.
