refactor(examples): drop 139 try/except guards that could never fire (#428)

129 example and showcase scripts wrapped `scene.eevee.taa_render_samples`
and Principled v2 / Wave input names (Coat Weight, Specular IOR Level,
Subsurface Weight, Detail Roughness) in `except AttributeError/KeyError/
Exception: pass`. Probed on 4.5.11 LTS, 5.1.2 and 5.2.1 LTS: every one of
those attributes and sockets exists, so the guards were dead code that
would silently swallow a typo in exactly the kind of name this repo
exists to get right. The statements now run unguarded.

Closes #405
