[FEATURE] Add "No follow" in links of Search Results Pager block

[Aryan-R-Patel]

Overview of feature request
This feature request involves adding the rel="nofollow" attribute to all links within the Search Results Pager block. The goal is to make bots not follow the links, which will prevent unnecessary and extensive resource consumption and crawling.

Note: To NOT force this behaviour (and provide the user with flexibility), we can add an option to toggle this in the config form.

What kind of user is the feature intended for?
Developer, Systems Administrator

What inspired the request?
The request was inspired by recent bot attacks and aggressive crawling behavior, and mainly aims to improve the bot management. Adding rel="nofollow" will prevent good bots from crawling deeply through our pages.

What existing behavior do you want changed?
Currently, the links are standard anchor tags without any rel="nofollow" attribute. We want to modify the output of these links so that they include rel="nofollow", to solve the purpose described in the overview.

Any brand new behavior do you want to add to Islandora?
Not entirely new behavior is being added. This is an addition of the attributes in existing links.

Any related open or closed issues to this feature request?
