[ruby/prism] Fix an incorrect range of Prism::Location when PM_ERR_RETURN_INVALID

This PR fixes the following incorrect range of Prism::Location when PM_ERR_RETURN_INVALID.

It may be hard to tell from the text, but this Ruby error highlights return:

$ ruby -e 'class Foo return end'
-e:1: Invalid return in class/module body
class Foo return end
-e: compile error (SyntaxError)

Previously, the error's Prism::Location pointed to end:

$ bundle exec ruby -Ilib -rprism -ve 'p Prism.parse("class Foo return end").errors'
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22]
[#<Prism::ParseError @type=:return_invalid @message="invalid `return` in a class or module body"
@location=#<Prism::Location @start_offset=17 @length=3 start_line=1> @level=:fatal>]

After this fix, it will indicate `return`.

```console
$ bundle exec ruby -Ilib -rprism -ve 'p Prism.parse("class Foo return end").errors'
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22]
[#<Prism::ParseError @type=:return_invalid @message="invalid `return` in a class or module body"
@location=#<Prism::Location @start_offset=10 @length=6 start_line=1> @level=:fatal>]

For reference, here are the before and after of Prism::Translation::Parser.

Before:

$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve 'p Prism::Translation::Parser33.parse("class Foo return end")'

This PR ensures that the originally intended return is highlighted as it should be.
