Masataka Pocke Kuwabara 76914d474d Fix error when default gem is loaded from `-r` option 
This patch fixes an error when a default gem that will be migrated to
a bundled gem is loaded from `-r` option.

Problem
===

`bundle exec ruby -rostruct -e ''` unexpectedly raises the following error:

```console
$ ruby -v
ruby 3.4.0dev (2024-04-08T02:39:00Z master 6f7e8e278f) [arm64-darwin21]
$ bundle init && bundle install
$ bundle exec ruby -rostruct -e ''
/Users/kuwabara.masataka/.rbenv/versions/trunk/lib/ruby/3.4.0+0/bundled_gems.rb:111:in 'Gem::BUNDLED_GEMS.warning?': undefined method 'find' for nil (NoMethodError)

      caller = caller_locations(3, 3).find {|c| c&.absolute_path}
                                     ^^^^^
        from /Users/kuwabara.masataka/.rbenv/versions/trunk/lib/ruby/3.4.0+0/bundled_gems.rb:75:in 'block (2 levels) in Kernel#replace_require'
```

Solution
===

This patch uses a safe navigation operator to fix this problem. By this
change, the command will show the warning message correctly.

```console
$ bundle exec ruby -rostruct -e ''
warning: ostruct was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.5.0. Add ostruct to your Gemfile or gemspec.

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers
