Add the message body to the pages tab in replayweb

Is your feature request related to a problem? Please describe. Upon opening a WARC file of an archived email message in Archive Web.Page, I found the "Pages" tab to be empty, despite there being numerous (sometimes hundreds) of URLs listed under the URLs tab. To locate the email body, users are required to filter through by searching for "HTML" that contains "mailto." This process can be challenging for many users.

Describe the solution you'd like Incorporating the message body directly into the pages tab on ReplayWeb would be beneficial, considering the complexity of navigating through WARC files.

Describe alternatives you've considered Clarify in the user documentation that to access the email body, users should apply a filter by searching for "HTML" that includes "mailto."
