fix(shared-data): restore sign-in testimonial with correct avatar (#50466)

## Before

The Studio sign-in page
(`apps/studio/components/layouts/SignInLayout/SignInLayout.tsx`) shows a
rotating testimonial next to the auth form, picking one tweet object
from `packages/shared-data/tweets.ts` and rendering its `text`,
`handle`, and `img_url` together. Two entries in the data file pointed
at the *same* avatar image file (`JwLEqyeo_400x400.jpg`): one attributed
to `orlandopedro_` and one to `pontusab`, despite being different people
with different quotes. That file was confirmed (byte-for-byte) to
actually be `pontusab`'s real photo, so `orlandopedro_` had no correct
avatar checked in.

## First attempt

The initial fix (this PR's first commit) removed the `orlandopedro_`
entry entirely, since no verified avatar was available for that handle
at the time, following this repo's precedent (PR #38500) for resolving
this class of bug by deleting the erroneous entry.

## Correction

Jordi confirmed the correct profile picture for `orlandopedro_` in the
Slack thread, so instead of leaving the entry deleted, this PR now
**restores** it with the correct avatar:
- Added `apps/www/public/images/twitter-profiles/ZjIOtCGg_400x400.jpg`
(downloaded from the user-provided URL), following the existing filename
convention used by other entries in that directory (the image's own
Twitter CDN slug + `_400x400.jpg`).
- Restored the `orlandopedro_` object in
`packages/shared-data/tweets.ts` (same quote text, handle, and URL as
originally) with `img_url` now pointing at the new, correct image file.

The `pontusab` entry is untouched throughout.

## Test plan

- Verified the restored object diffs as an exact re-add of the
originally removed entry, with only `img_url` changed to the new file.
- Verified the downloaded image is a valid 400x400 JPEG.
- Verified brace/object structure of `tweets.ts` is balanced after the
edit.
- Could not run `pnpm install` in this environment (blocked on
`npm.jsr.io`), so lint/prettier/build were not executed; verified the
diff manually instead.
