Updated mcmeta to include 1.21.4 update, no other changes

Updating to 1.21.2

Adds air bubbles, item highlights, high contrast tooltips, better food haunches while under the hunger effect. Also fixes some issues with the menus that I hadn't fixed in earlier versions

Air bubbles

Haunches

Bundles

Item Highlights and tooltips

• Adds support for axiom's in-game gui textures

• Adds support for the Legacy4J Mod
• arichornloverALT contributed this in PR 1

Updated mcmeta to 1.21

No other changes

Referenced the shaders (stole them) from Default Dark Mode - Extremely cool project I highly recommend using

• updated to 1.20.5
• Was unable to update the shaders, the text in UIs is currently not high contrast, I apologize for this.

Adds support for the crafter A lot of style adjustments, gallery images have been updated

Adjusts a lot of textures within the advancement screen and recipe book screens to be more contrasting and less washed out I will be working on adjusting the inventory screens soon as well

• Updates version to pack version 16
• Migrates to new sprite format

Made some minor texture adjustments

New textures/Adjusted textures

Lighter gray for the light dirt background and buttons

Changed the haunch texture back to 'normal' haunches, so it doesn't conflict with mods like appleskin - texture is modified to fit with the simplified textures of the overall GUI

Made the toast texture gray instead of cyan, but it's still ugly

Attached the line for the tabs of the recipe book, instead of having it cut in, and made the X black instead of red

Version 1.3:

Additions:

• The arrows in the world selection screen
• The arrows in the resource pack selection screen
• The arrows in the server selection screen
• The demo screen (may actually be unreadable, I wasn't able to test on my own, if the text doesn't show as white on it, I might need to edit it)
• Toasts (The text looks bad on it, if someone knows how to edit text shaders, I would appreciate any PRs regarding that)
• Player interaction screen

Contains a small fix for the villager trade menu, which adds a slider outline since there's room for that now

Bumps mcmeta version to 15

Made the box lines surrounding the inventories greyscale so that they looked a bit less weird separating the dark surrounding color from the light item squares

First version, probably has some issues lol Github
