Don't add "..." to every label of 3 or more characters

[Neradoc]

The actual length of the text was not tested in set_text, the mere existence of maxlen was enough to shorten the string, or add "..." if the string was shorter than maxlen - 3.

Thanks for this fix!

I tested this successfully with a pyportal and this code by tweaking maxlen value:

import board
from adafruit_pyportal import PyPortal


# Create the PyPortal object
pyportal = PyPortal()

# Set display to show REPL
# board.DISPLAY.show(None)

pyportal.add_text(
    text="Hello World", 
    text_color=0xFFFFFF, 
    text_position=(50, 50),
    text_maxlen=8
)

while True:
    pass

Confirmed the issue noted and the fix from this change.
