fix(cliff): Fix TOML parse errors in cliff.toml

Fixed unescaped backticks causing TOML parse errors:

Errors found:
- Line 68: `config.ini` -> 'config.ini'
- Line 40: `RainingKeysPython.zip` -> 'RainingKeysPython.zip'
- Line 41: `RainingKeysPython-debug.zip` -> 'RainingKeysPython-debug.zip'

TOML parsing rules:
- Backticks ` need to be escaped in TOML
- Single quotes ' don't need escaping in multiline strings
- Double quotes " don't need escaping in multiline strings
- Replace: ` -> ' or \` for backticks

Changes:
1. Line 40: Changed file path backticks to single quotes
2. Line 41: Changed file path backticks to single quotes
3. Line 68: Changed config file backticks to single quotes

This should resolve 'missing escaped value' errors in cliff.toml.
