"Data mode" and "Load mode" aren't capitalized while "Save Mode" and "Corner Mode" are

The Bug

With the fix of MC-190102, Save Mode and Corner Mode were capitalized in the structure block interface, but it looks like Data mode and Load mode were missed

Steps to Reproduce

• Summon two structure blocks, one of which is in "data" mode and the other in "load" mode.

  /setblock ~1 ~ ~ minecraft:structure_block[mode=data]
  /setblock ~1 ~ ~1 minecraft:structure_block[mode=load]
  

• Open each of them and locate the "Data mode" and "Load mode" texts.
• Take note as to whether or not the word "mode" in the "Data mode" and "Load mode" texts within the structure block GUI isn't capitalized.

Observed Behavior

The word "mode" in the "Data mode" and "Load mode" texts within the structure block GUI isn't capitalized.

Expected Behavior

The word "mode" in the "Data mode" and "Load mode" texts within the structure block GUI would be capitalized.
