There are no shadows on text displayed within the scoreboard overlay

The Bug:

There are no shadows on text displayed within the scoreboard overlay.

This is an issue because when the "Text Background Opacity" slider is set to "0%", the text can be quite difficult to read, so having a shadow displayed on all text within the scoreboard overlay would resolve this problem.

Steps to Reproduce:

1. Navigate to your accessibility settings menu and set the "Text Background Opacity" slider to "0%" and the "Text Background" button to "Everywhere".
2. Display some text on the scoreboard by using the commands provided below.

   /scoreboard objectives add MC-240722 dummy

   /scoreboard objectives setdisplay sidebar MC-240722

   /scoreboard players set @s MC-240722 123456789
   

3. Look closely at the text displayed within the scoreboard.
4. Take note as to whether or not there are any shadows on text displayed within the scoreboard overlay.

Observed Behavior:

There are no shadows on text displayed within the scoreboard overlay.

Expected Behavior:

There would be shadows on text displayed within the scoreboard overlay.
