False Positive for `Lint/ImplicitStringConcatenation` with prism

[pjsk-stripe]

Expected behavior

Lint/ImplicitStringConcatenation behaves strangely with prism in the situation below. With prism turned off, it doesn't report an error.

I imagine this is some combination of the \n and heredocs. But strangely the prefix Something: is determining the output.

Actual behavior

Steps to reproduce the problem

$ rubocop -V
1.63.4 (using Prism 0.27.0, rubocop-ast 1.31.3, running on ruby 2.7.2) [arm64-darwin22]

AllCops:

RuboCop version

Include the output of rubocop -V or bundle exec rubocop -V if using Bundler.
If you see extension cop versions (e.g. rubocop-performance, rubocop-rspec, and others)
output by rubocop -V, include them as well. Here's an example:

$ rubocop -V
1.63.4 (using Prism 0.27.0, rubocop-ast 1.31.3, running on ruby 3.3.0) [arm64-darwin23]
