address back button nav issues

[wbholland]

in the previous change (https://github.com/KenEucker/biketag-vue/issues/208), pressing the back button failed to update the contents of this page. This is my try at fixing that.

PR Summary

• Addition of 'watch' import in Players.vue This change includes importing a new feature watch for better data tracking and operations.

• Update of onMounted function The onMounted function, which runs once the component is fully loaded, has been updated. It now calls a new function called validateQuery to ensure our data query is valid.

• Inclusion of new validateQuery function A new function validateQuery is introduced as part of this PR which checks to see if the perPage value, which indicates how much data is displayed on each page, is valid. If it's not, it resets the page back to 1. This is to prevent errors and ensure that data is displayed correctly.

• Addition of watcher in route Finally, a watcher has been incorporated that monitors route changes in our app. It updates the needed data as per the changes on route. This can lead to smoother user navigation and overall better user experience.
