Replace windows-2019 by windows-2025 as GitHub action runner

[apupier]

for the alternate OS tested
The Windows 2019 is now deprecated
actions/runner-images#12045

Note also that:

NOTICE: windows-latest requests are being redirected to
windows-2025-vs2026 by June 15, 2026

so at that point in time will need to switch to windows-2022 and windows-latest

Description

Target

• I checked that the commit is targeting the correct branch (Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally from root folder and I have committed all auto-generated changes.
