Use Boavizta API 1.3.8

[demeringo]

Problem

We use API 1.3.7

Solution

Target 1.3.8 https://github.com/Boavizta/boaviztapi/releases/tag/v1.3.8

Among other things, API 1.3.8 changed the lifespan of AWS Server, so we will have to

• update our integration tests to match the new values.
• Issue a warning in the changelog / release notes to explain this change of returned values to end users.
• Maybe also mention the support of new CPU's (Apple M1 and M2 and Graviton 4)
