docs: improve documentation clarity and consistency
- Change "GitHub Action" to "A GitHub Action" for clarity. - Update phrasing from "built using" to "built with" for consistency. - Revise "Make sure to follow the below steps" to "Follow the steps below" for improved readability. - Modify "best practice is create" to "It is best practice to create" for grammatical correctness. - Change "Add newly generated key into Authorized keys" to "Add the newly generated key to the Authorized keys" for clarity. - Update "Copy Private Key content and paste in Github Secrets" to "Copy the Private Key content and paste it into GitHub Secrets" for consistency. - Change "install `clip` command" to "install the `clip` command" for grammatical correctness. - Revise "See the detail information about" to "See detailed information about" for improved readability. - Update "A note from one of our readers" to "Note: Depending on your version of SSH" for clarity. - Change "Make sure that your key algorithm of choice is supported" to "Ensure that your chosen key algorithm is supported" for conciseness. - Revise "Alternatively, `ed25519` keys are accepted by default" to "Alternatively, `ed25519` keys are accepted by default in OpenSSH" for clarity. - Update "if you are running a command in a non interactive shell" to "If you are running a command in a non-interactive shell" for grammatical correctness.
