Rename WordPress.com connection errors mentioning Jetpack

[sukafia]

User story

As a user of the Google Listings & Ads extension, I occasionally encounter errors when there's an issue with the WordPress.com connection. These errors mention "Jetpack," which causes confusion and concern among users who may not be familiar with the relationship between Jetpack and WordPress.com in the context of GL&A.

When I encounter an error relating to WordPress.com, I want to be presented with clear and concise messages that explicitly mention WordPress.com as the service requiring reconnection. This will help me understand that the issue lies with the connection to WordPress.com and is not necessarily dependent on the Jetpack plugin.

By renaming instances of "Jetpack" to "WordPress.com" in error messages and prompts, I will feel more confident that I can resolve connection issues without the need for an additional plugin. This clarity will improve my overall experience with the GL&A extension and reduce the likelihood of me abandoning it in favor of alternatives.
