security: clear serialize-javascript High alert (terser-webpack-plugin refresh) (#21397)

## What

Clears the High `serialize-javascript` alert (GHSA-5c6j-r48x-rmvq) — a
plain in-range refresh, **no resolution**, only `yarn.lock` (net −22
lines).

`serialize-javascript@6.0.2` was pulled only by
**`terser-webpack-plugin@5.3.16`** (webpack's minifier). The patched
line (7.x) is outside terser's old `^6.0.2` range — but
**`terser-webpack-plugin@5.6.1` dropped the `serialize-javascript`
dependency entirely**, and webpack already requests
`terser-webpack-plugin@^5.3.16` (which allows 5.6.1).

So `yarn up -R terser-webpack-plugin` → 5.6.1 removes the vulnerable
6.0.2; only the patched **7.0.5** (twenty-website's direct dep) remains.

## Verification
- No `serialize-javascript@6.x` left in the lockfile
- `nx build twenty-server` (exercises the `@nestjs/cli` webpack/terser
path) ✅
- `yarn install --immutable` clean

yarn.lock
