Fix: lex now throws error on unbalanced closing parentheses (issue #11982) (#12098)

- Fixes issue #11982 

# Description
Expressions with unbalanced parenthesis [excess closing ')' parenthesis]
will throw an error instead of interpreting ')' as a string.

Solved he same way as closing braces '}' are handled.

# User-Facing Changes
- Trailing closing parentheses ')' which do not match the number of
opening parentheses '(' will lead to a parse error.
- From what I have found in the documentation this is the intended
behavior, thus no documentation has been updated on my part

# Tests + Formatting
- Two tests added in src/tests/test_parser.rs
- All previous tests are still passing
- cargo fmt, clippy and test have been run

Unable to get the following command run
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library
