Bastin 24e51f283b Add startup version log (#16283) ...

**What does this PR do? Why is it needed?**
Adds a log mentioning the name and the version of the app: 

Beacon-chain:
```
[2026-01-26 12:03:12.91]  INFO main: Prysm Beacon Chain started. [Prysm/Unknown/Local build. Built at: Moments ago] prefix=main
```
Validator:
```
[2026-01-26 12:00:07.38]  INFO main: Prysm Validator started. [Prysm/v7.1.2/7950a249266a692551e5a910adb9a82a02c92040. Built at: 2026-01-06 18:47:23+00:00] prefix=main
```

**Note:** I've removed the previous two logs that mentioned version in
favor of these new ones. I've also moved the initialization logs of
persistent log file and ephemeral log file to DEBUG.

**Which issues(s) does this PR fix?**
