Fixed migration causing issues with mariadb

[marcusmoore]

This PR amends a migration that was included in #15714 that does not work on older versions of mariadb (v10 and below I believe).

That PR introduced a json column and mariadb (<v11) doesn't like that so this PR changes it to a text type like we have elsewhere in the application.

Some people may have already successfully run the migration and so another migration was created to "change" the column to text. To the best of my knowledge and from testing, if the column is already text then the operation is essentially a no-op so it shouldn't cause any issues "changing" the column from "text" to "text".

PR Summary

• Updated 'options' Column Within the 'report_templates' Table
  Changed the data type of 'options' column from json to text enhancing compatibility with earlier versions of MariaDB.

• Introduced New Migration File
  A new file 2025_01_06_210534_change_report_templates_options_to_column_text_field.php was added. This enables a persistent change in the type of the 'options' column to text. A key objective behind this move was to foster consistent data handling across multiple database versions.
