fix(javascript): sync JSDoc continuation patterns with TypeScript language config (#308433)

fix(javascript): sync JSDoc continuation patterns with TypeScript config

Both language configuration files carry a comment stating they should
stay in sync with each other, but two JSDoc-related regex patterns had
drifted in the JavaScript file.

1. `unIndentedLinePattern` — the third alternative that matches an
   in-progress JSDoc continuation line (`* comment text`) required a
   literal space immediately before the `*`:
     Before: `^(\\t|[ ])*[ ]\\*([ ]...`
     After:  `^(\\t|[ ])*\\*([ ]...`

2. `onEnterRules` — the `beforeText` pattern for the rule that appends
   `* ` when pressing Enter inside a JSDoc block had the same extra
   space requirement.

The TypeScript configuration does not require this leading space, which
means that JSDoc comments whose `*` continuation lines are indented with
tabs only (e.g. `\t* line`) were recognized correctly in TypeScript
files but not in JavaScript files. After this change both files use the
same permissive pattern.

Also aligns the `wordPattern` character-class order (`@~` → `@~`,
purely cosmetic, no behavioral difference).
