feat(lenovo): add broad 'Lenovo TB' prefix for modern tablets

[serbanghita]

Summary

• Adds Lenovo TB| catch-all prefix to the LenovoTablet regex, matching all modern Lenovo tablets that use TB-XXXX (hyphenated) or TBXXXFU (non-hyphenated) naming formats
• Eliminates the need to individually list every new Lenovo tablet model code — 20+ models from 2023-2026 are now automatically covered
• Adds 5 test fixtures for recent models not individually listed (TB330FU, TB370FU, TB351FU, TB321FU, TB311XU)

Context

Addresses PR #994 ("Add new 'Lenovo TB' user-agent" by @nstwfdev) and related issues #871, #855. Newer Lenovo tablets were not detected because the existing regex only matched Lenovo TAB (old naming) or specific model codes. This change adds the missing Lenovo TB broad prefix while keeping all existing individual entries intact.

Lenovo tablet naming conventions

Era	UA Format	Example	Matched by
Pre-2016	Lenovo TAB ...	Lenovo TAB 2 A7-30F	Lenovo TAB (existing)
2016-2022	Lenovo TB-XXXX	Lenovo TB-J606F	Individual model codes (existing)
2022+	Lenovo TBXXXFU	Lenovo TB330FU	Lenovo TB (new)

False positive risk

Minimal — a UA containing Lenovo TB is virtually always a Lenovo tablet. The prefix is always followed by either a hyphen+model code or a numeric model code.

Test plan

• All 1877 existing tests pass
• 5 new test fixtures for models only matched by the broad prefix
• phpcs lint passes
• Review regex change in src/MobileDetect.php line 567

Pull request overview

This PR expands Lenovo tablet detection by adding a broad Lenovo TB prefix to the LenovoTablet tablet-regex, so modern Lenovo tablet model strings (e.g., TB-XXXX and TB###FU) are classified as tablets without needing to enumerate every new model code.

Changes:

• Update LenovoTablet detection regex to include a broad Lenovo TB prefix.
• Add 5 new Lenovo tablet UA fixtures (TB330FU, TB370FU, TB351FU, TB321FU, TB311XU).
• Regenerate tests/ualist.json (including its hash) to reflect the updated provider fixtures.

I feel tiny bit of unconfortable to allow a broad regex like Lenovo TB, but as long as there are tests we're gucci
