BREAKING(text): align to single-export file pattern

[kt3k]

This PR changes text package to make it adhere to single-export file pattern.

Addresses the feedback in the stabilization review at #5209 (comment)

What's changed

The case utilities (toCamelCase, toKebabCase, toSnakeCase, toPascalCase) are now exported from single-export files, instead of @std/text/case.

Motivation

The standard library generally follows single-export pattern (A single file exports a single API), but these utilities didn't follow that rule without any clear reason. This change makes them follow the pattern to improve the consistency of export structure of the standard library.

Migration

-import {
-  toCamelCase,
-  toKebabCase,
-  toPascalCase,
-  toSnakeCase,
-} from "@std/text/case";
+import { toCamelCase } from "@std/text/to-camel-case";
+import { toKebabCase } from "@std/text/to-kebab-case";
+import { toPascalCase } from "@std/text/to-pascal-case";
+import { toSnakeCase } from "@std/text/to-snake-case";

Note: These utilities are also exported from @std/text (The top-level of the package). If you import them from there, you're not affected by this change.
