Remove redundant photon-targeting JNI library load (#2220)

## Description

#2137 made it so `TestUtils.loadLibraries()` loads both WPILib and
photon-targeting, which is used in Main.java to load libraries, but it
left the separate photon-targeting load in Main. This removes the extra
library load, since it's covered by `TestUtils.loadLibraries()`.

## Meta

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with settings back to v2025.3.2
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added
