AI Summary: Enhance the `pagure-exporter` tool to handle `@` symbols in issue titles during migration to GitLab. Currently, the tool replaces `@` symbols in comments but not titles, leading to unintended notifications on GitLab if the `@` symbol references a valid GitLab user or group. The enhancement should prevent these notifications by modifying the title before import, ideally replacing `@` with `&&` consistently with comment handling.

AI Summary: Update the documentation for the `pagure-exporter` tool to include details about the newly added source and destination platform flags. This involves adding a description of these flags to the existing documentation, likely within the Usage section, explaining their purpose and how to use them. The documentation should clearly explain how these flags affect the migration process.
