The pillager does not have a unique spawn egg texture

Partner Rank:
3

Summary:
The pillager does not have it's own spawn egg and does not use the logical "egg_pillager". The vanilla file refers to colour codes rather than pointing to a file, like all other mobs do.

Impact:
This prevents the ability for texture packs to customise the spawn eggs to be unique which is causing the textures to be inconsistent within Tiny Footprints. It will affect any other texture packs too.

Repro Steps:

• Look within the game files
• Observe no "egg_pillager" item file
• Observe the Entity json using colour codes

Observed Results:
It appears creators are not able to create custom textures for the pillager spawn egg

Expected Results:
The pillager spawn egg is able to be uniquely textured like all other spawn eggs in the game. The pillager receives it's own png and the entity file points towards said png

Screenshots/Videos attached:
Yes

Regression Builds:
Since inception

Notes
Although the base spawn eggs textures allow for creators to have a custom generic pattern (as seen in the screenshot), this is limiting and inconsistent with all other eggs.
