language: Add auto-surround for Plain Text, JSON, and JSONC (#42631)

**Summary**
When users selected text and pressed opening brackets (`(`, `[`, `{`),
the text was deleted instead of being wrapped.

- Added bracket pairs: `()`, `[]`, `{}`, `""`, `''` with `surround =
true`
- Added `surround = true` to existing bracket pairs
- Added `()` bracket pair

**Production Build Fix** (`crates/languages/src/lib.rs`)
- Fixed bug where `brackets` config was stripped in non-`load-grammars`
builds
- Preserved `brackets: config.brackets` in production mode

Closes #41186
