feat(attributes): Add file.path and file.size

[buenaflor]

Add the OTel-aligned file.path and file.size attributes to the file namespace.

Both attributes are already defined in the OpenTelemetry semantic conventions registry, so per the contributing guidelines we reuse the OTel names and types rather than introducing Sentry-specific synonyms, and set is_in_otel: true.

• file.path — string, e.g. /home/user/example.txt
• file.size — integer (bytes), e.g. 1024
