[FEATURE]: docs(ko): improve natural Korean phrasing in ecosystem, enterprise, formatters, and github docs

[Seungjun0906]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

I want to improve wording quality in the Korean docs so they read naturally for Korean developers while preserving technical meaning.

Scope:

• packages/web/src/content/docs/ko/ecosystem.mdx
• packages/web/src/content/docs/ko/enterprise.mdx
• packages/web/src/content/docs/ko/formatters.mdx
• packages/web/src/content/docs/ko/github.mdx

Expected outcome:

• Keep original technical meaning and Markdown structure intact
• Improve readability with natural Korean phrasing
• Keep terminology consistent with the glossary
• Preserve code blocks, commands, and URLs exactly as-is

This is a docs-only improvement and does not change runtime behavior.
