feat(mods/pride_flags): add an in-repo mod for pride flags

[RobbieNeko]

Purpose of change

Pride flags seemed like an appropriate thing to add in an in-repo mod and based on our community, it seemed like it would be appreciated.

Describe the solution

• Adds transgender, aromantic, asexual, bisexual, intersex, lesbian non-binary, pansexual, gay (men), and genderfluid pride flags as well as the original rainbow flag.
• Adds recipes for the above flags (adapted from the recipe for a blanket)
• Adds an itemgroup containing these flags to the major itemgroup containing American flags

Describe alternatives you've considered

• Making it mainline instead of a mod
  Considering our lack of a variants system and how we all saw the drama that came up in the DDA PR to add pride flags to their mainline, I believe an in-repo mod is a better solution.

• Adapt the DDA uncraft recipe as our crafting recipe for the pride flags
  7 sheets just looked really excessive to me.

Testing

The game loads, pride flags show, the crafting is a go, and the itemgroups behave as usual.

Additional context

Semantic PR titles continue to baffle me, hecc

[RobbieNeko]

Ehh, oh well. Semantic PR is gonna get caught up over semantics

[scarf005]

semantic PR complains because semantic.yml isn't updated yet.

[scarf005]

- transFlag
+ trans_flag

a bit of a nitpick, but generally mod id and item ids follow snake_case convention.
it's not a rule set in stone, but being consistent is nice.

[RobbieNeko]

Figured, haha. I'm just used to using camel case. Will go on ahead and change it to snake_case on your suggestion

[scarf005]

also don't worry about semantic PR failing, it'll fail till it's merged (because the check is done using main branch's semantic.yaml not this PR's semantic.yaml)

[RobbieNeko]

There, the case should now hopefully be appropriately snaked
Including the mod Id, so might want to adjust it in that semantic.yml file again

[scarf005]

thanks, one more tiny nitpick: directory name isn't snake_case but Kebab-Case.

[RobbieNeko]

To be fair, the directory names seem to have more variance with regards to that. But I will gladly comply

[scarf005]

@chaosvolt i think it'll be ready to merge after loadtest, failure in semantic PR check can be ig ored (due to limitation it always fail when adding new mod)

[chaosvolt]

1. Load-tested with mod.
2. Spawned in the last flag sprited in the mod_tileset to confirm it was the expected sprite.
   
   Layering will as always make me screm but there's nothing one can really do to fix that, you wear your messenger bag over blankets and US flags too and the layering looks equally odd anyway:
   

[RobbieNeko]

Oops, chaos accidentally revealed that that sprite got offset on the y-axis somehow
Lemme just fix that, sorry

[RobbieNeko]

Good thing Chaos happened to choose that one specific flag to test with, given that only it had its y-axis wonky xD

[RobbieNeko]

@chaosvolt So sorry, could you please re-review/approve this? Your testing just happened to reveal that the genderfluid flag's sprites somehow got offset on the y-axis, so I had to fix that real quick
