CPLAT-5632 Downgrade parse error to fine so as to not fail build unnecessarily

[greglittlefield-wf]

Motivation

Syntax errors in the example dir cause the OverReact builder to unexpectedly fail the build when running pbr test

For example:

$ pbr test -- test/foo_test.dart
[INFO] Generating build script completed, took 329ms
[INFO] Reading cached asset graph completed, took 548ms
[INFO] Checking for updates since last build completed, took 973ms
[INFO] Running build completed, took 404ms
[INFO] Caching finalized dependency graph completed, took 301ms
[SEVERE] over_react:overReactBuilder on example/viewport/main.dart (cached):
There was an error parsing the compilation unit for file: w_virtual_components|example/viewport/main.dart

Changes

Downgrade parse error to fine so as to not fail build unnecessarily

If they're problematic, these errors will be handled further
down the line (e.g., build_web_compilers).

This prevents syntax errors in examples from failing test
compilation.

Release Notes

• Avoid failing the build unnecessarily due to parse errors
