`URI::RFC3986_PARSER.inspect` and `URI::RFC2396_PARSER.inspect` raised
`Ractor::IsolationError` when called from a non-main Ractor:
Ractor.new { URI::RFC3986_PARSER.inspect }.value
#=> can not access class variables from non-main Ractors
# (@@to_s from URI::RFC3986_Parser)
Ractor.new { URI::RFC2396_PARSER.inspect }.value
#=> can not access non-shareable objects in constant
# URI::RFC2396_Parser::TO_S by non-main ractor
Both parsers kept `Kernel.instance_method(:to_s)` at the class level, in a
class variable and in a constant respectively. An `UnboundMethod` is not
shareable, so neither can be read from a non-main Ractor.
`UnboundMethod` is Ractor-shareable only Ruby 4.0. And, parser's inspect only for
debug and performance isn't so important, I think
So this commit changes not to held the method and just call it in the
method.
