fix(content): remove extra “to” from inaccurate fee alert (MetaMask#35975)

## **Description**

<!-- mms-check: type=text required=true -->

The live inaccurate-fee warning said “We suggest you to input,” which is
ungrammatical. This removes the extra “to” and updates the exact-string
unit assertion. No interpolation, styling, or component behavior
changes.

Feature: inaccurate fee warning

  Scenario: fee estimation fails
    Given transaction simulation cannot estimate the fee
    When the estimated fee alert is shown
    Then the message says “We suggest you input a custom gas limit”
```

Automated verification: `yarn jest
app/components/Views/confirmations/hooks/alerts/useGasEstimateFailedAlert.test.ts
--runInBand --coverage=false`

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Copy-only change to English locale text and a matching test string; no
runtime or security impact.
> 
> **Overview**
> Fixes grammar in the **inaccurate fee** warning shown when gas
estimation fails: the copy now reads “We suggest **you input**” instead
of “We suggest **you to input**.”
> 
> The change is in `locales/languages/en.json` under
`alert_system.gas_estimate_failed.message`, which
`useGasEstimateFailedAlert` already loads via `strings()`. The unit test
expectation in `useGasEstimateFailedAlert.test.ts` is updated to match.
No alert logic, UI, or interpolation changes.
