Fixed #13256 - Added option to switch to localStorage instead of cookies

[snipe]

This adds the ability to switch from cookieStorage to localStorage or sessionStorage in bootstrap table, which should be useful for folks with a LOT of custom fields hidden.

I set it to default to cookieStorage so for most people it won't break their existing remembered items.

PR Summary

• Addition to .env.example file
  A new environment variable BS_TABLE_STORAGE has been defined. It's set to cookieStorage, indicating the type of storage mechanism used, possibly for saving user preferences or sessions.

• New configuration in config/session.php file
  A configuration option bs_table_storage was introduced. This corresponds to the mechanism for storing session information for users, as defined with the previously mentioned environment variable.

• Updates to resources/views/partials/bootstrap-table.blade.php file
  The session configuration is now being used in the file responsible for rendering bootstrap tables on the front-end. The change suggests the session's storage method is now central to the table's functionality, probably affecting how user interactions with the table are stored and recalled.
