[MC-214700] Spore blossom top leaf texture is not mirrored correctly from behind

For a comprehensive list of other examples of issues with 2D planes in models not being mirrored as expected, click here.

The plane composing the top attachment for spore blossoms does not mirror on the back as one would expect, resulting in physical/illogical weirdness.

Place a spore blossom
View a specific section of the leaf, preferably a 2x2 area on the corner
View the exact same section of that texture plane on the direct opposite side
Note that the exact texture pattern at that position is different, even though it should be the same

The resource pack attached to MC-237445 fixes this issue completely, alongside fixing multiple other issues with flat plane models.

The attached spore_blossom.json can also be used, however it "fixes" ~~MC-214185~~ as well, which has since been considered intended.
