What does this PR do?

Korean docs wording improvements for the following pages:

• 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

I rewrote awkward literal translations into more natural Korean while preserving technical meaning and document structure.

This PR only updates docs wording/terminology consistency and keeps code blocks, commands, links, and headings intact.

How did you verify your code works?

• Reviewed each diff against the English source docs.
• Checked MDX structure integrity (frontmatter, headings, tables, code blocks, links).
• Confirmed this PR is docs-only and does not change runtime behavior.
