Fix typos in roadmap content and repair a broken wgpu docs link

[paul-madut]

Spelling fixes across 15 roadmap content files. 16 lines changed, no content added or removed.

The one functional fix - rust/wgpu-rs had a link that cannot resolve:

- [@article@wpgu docs](hhttps://docs.rs/wgpu/latest/wgpu/)

hhttps:// is not a valid scheme, so the link is dead. The label was also wpgu (transposed). Both fixed.

Headings

• Role Based Acccess Control -> Access (kubernetes)
• Priorization Frameworks -> Prioritization (product-design)
• Exitting / Exit Codes -> Exiting (nodejs)

Prose

• terraform: "cannot delare count" -> declare
• engineering-manager: "faciliate these sessions" -> facilitate
• redis: "a variety of platofrm" -> platforms
• game-developer: CYMK -> CMYK, and magyenta -> magenta. The acronym was also expanded in the wrong order ("Cyan, Yellow, Magenta, Black"), which is now "Cyan, Magenta, Yellow, Black" to match CMYK. The same paragraph already spells it CMYK correctly two sentences later.

Resource labels - each corrected to match the title of the page actually linked

• Task Schedulling -> Scheduling (laravel, links to /docs/12.x/scheduling)
• Understandig Virtual Tables -> Understanding (cpp, links to understanding-virtual-tables)
• Comparison Opearators -> Operators (c, x2)
• Arrrays -> Arrays (ruby)
• Databases & Persistance -> Persistence (swift-ui)
• Google Coud DNS -> Google Cloud DNS (network-engineer, also removes a double space)
• Built-in commadns -> commands (claude-code)

Filenames are untouched - three of them contain the misspelling too (priorization-frameworks, exitting--exit-codes, task-schedulling), but renaming them would break the roadmap node IDs, so I left them alone.

I also left several spellchecker hits alone because they are correct as written: BRIN, TestNG, BLoC, MongoDB $nin, Vert.x, LOD, and FPR.
