Running bundle exec pod install is create an unnecessary change in the Gemfile for ruby

Question

I ran ruby -v on My system's root and the version I got is

ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22]

I verified that my project is using same version by navigating to my project directory and running ruby -v again. I got-

ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22]

However, anytime I do, bundle exec pod install, I get a change on my gemfile.lock file.

Any anyone help me with the issue.
