Fix gemspec ruby version checks (#259)

* Fix: Conditional dependency logic in gemspec

- Fixed the logic in the gemspec file to correctly compare the current Ruby version with the required version.
- Replaced string comparison of `RUBY_VERSION` with `Gem::Version` for better semantic version handling.
- Addressed edge cases, such as "3.10" being greater than "3.2".

Why:
The previous comparison caused a `LoadError` for `syntax_suggest` on Ruby 3.1.6 due to incorrect string-based version comparison. RUBY_VERSION returns a string, not a comparable version, breaking the current comparison in some cases.

* Fix: Update `syntax_suggest` dependency version constraint

- `”syntax_suggest", "~> 1.1.0"`  to `”syntax_suggest", ">= 1.1.0"` in the gemspec

Why:
Allows greater flexibility for users by supporting newer versions of `syntax_suggest` beyond the `1.x` range, especially as 2.x requires ruby >= 3.0
