Fix dumping when there are #$ in array elements.

[shanyungyang]

There is special treatments to #$ when dumping string values, but this does not work properly for arrays.

require 'toml-rb'
puts TomlRB.dump(value: '#$')   # value = "#$"
puts TomlRB.dump(array: ['#$']) # array = ["\#$"]

This PR fixes array dumping by passing array elements to the to_toml method instead of calling inspect.

@shanyungyang thank you for your contribution!

Would you mind fixing the linter, and as an extra favour, fixing the style-inconsistency that I left in the elsif clauses?
Basically, use parenthesis after the is_a? with all the options 🙏 .

elsif obj.is_a? Array -> elsif obj.is_a?(Array)
