fix: update WASI version references from 0.2.6 to available 0.2.3

Resolves CI failure where Go component was importing wasi:io/[email protected]
but only 0.2.3 is configured in the WASI dependencies. Updated:

- Go component calculator.wit: wasi:io/[email protected] → @0.2.3
- Documentation examples: consistent use of available 0.2.3 versions
- Example WIT files: align with actual configured dependencies
