fix(php): strip .000 milliseconds from WireMock datetime query params

[iamnamananand996]

Description

Refs: getbrevo/brevo-php#109

Fixes a datetime format mismatch between WireMock stubs and PHP SDK serialization that causes wire tests to fail. The shared mock-utils package generates datetime query parameter values using Date.toISOString() (e.g., 2022-01-02T00:00:00.000Z), but PHP's DateTimeInterface::RFC3339 format omits fractional seconds (e.g., 2022-01-02T00:00:00Z). Since WireMock's equalTo is an exact-match comparator, stubs for endpoints with datetime query parameters never fire.

Changes Made

• Added stripDatetimeMilliseconds static method to WireTestSetupGenerator that strips .000 from datetime-formatted query parameter values in WireMock stub mappings before writing wiremock-mappings.json
• Follows the same approach already used by the Python SDK generator (generators/python-v2/sdk/src/wire-tests/WireTestSetupGenerator.ts)
• Bumped PHP SDK version to 2.1.12

Testing

• Unit tests added/updated — no unit tests were added for the new method; the approach mirrors the Python generator's proven pattern
• Lint/type checks pass (pnpm run check)

Review Checklist

• Only query parameters are handled — if datetime values also appear as path parameters in WireMock equalTo matchers, those would still mismatch. Verify this is sufficient for the reported issue.
• Regex only matches .000 — non-zero fractional seconds (e.g., .500Z) are intentionally left untouched. This is correct since PHP's RFC3339 drops all fractional seconds, but would still cause a mismatch if the IR contains datetimes with non-zero millis. Unlikely in practice since autogenerated examples typically use round seconds.
• No changes to shared mock-utils — the fix is scoped to the PHP generator's post-processing step, avoiding impact on other generators.
