fix(templates): added missing CLOUDFLARE_ENV in cloudflare template when optimizing database (#14064)

### What?
Adds the missing `$CLOUDFLARE_ENV` env parameter when optimizing the D1
database after deploy.
Switched from `-e` to `--env` as `-e` doesn't handle it very well when
`$CLOUDFLARE_ENV` is empty.

### Why?
Running "PRAGMA optimize" tells D1/SQLite to refresh its statistics for
the query planner. This is crucial whenever an index is added or
removed.

### How?
By adding the "--env" parameter to the `wrangler d1 execute` command
