chore(deps): bump immutable

[jpan-box]

Ensure nested immutable under draft-js resolves to ^3.8.3 and drop the stale 3.7.6 lockfile entry.

Why a resolution

• draft-js / @types/draft-js pin immutable@~3.7.4.
• A normal bump can't reach the patched 3.x line for those nested deps.
• Top-level immutable@^4 (sass/devDependency) must stay on v4, so the override is scoped under draft-js (not a global pin).

Dep chain:

yarn why v1.22.22
[1/4] Why do we have the module "immutable"...?
[2/4] Initialising dependency graph...
[3/4] Finding dependency...
[4/4] Calculating file sizes...
info 
=> Found "immutable@4.3.9"
info Has been hoisted to "immutable"
info Reasons this module exists
   - Specified in "devDependencies"

info Disk size with unique dependencies: "784KB"
info Disk size with transitive dependencies: "784KB"
info Number of shared dependencies: 0
info 
=> Found "@types/draft-js#immutable@3.8.3"
info This module exists because "@types#draft-js" depends on it.

Steps taken

1. Added @types/draft-js/immutable resolution (^3.8.3) alongside existing draft-js/immutable; merged the stale immutable@~3.7.4 lock entry onto 3.8.3 (removed 3.7.6).
2. yarn install — Already up-to-date.
3. npx yarn-deduplicate yarn.lock then yarn install — lockfile stable.
4. yarn audit — no immutable versions below 3.8.3 remain in yarn.lock (nested installs resolve to 3.8.3; top-level dev/sass stays on 4.3.9).
5. Full test suite passes (976 suites, 11527 tests).

Summary by CodeRabbit

• Chores
  • Added a package resolution to improve compatibility with Draft.js type definitions.

Poem

A rabbit checks the lockfile tonight,
One type resolution now sits right.
The tar entry stays in view,
With tidy changes, small and true.
