Describe the changes you've made
I have Added a tag Search page where user is directed, if it clicks either tags on Mediacard or explicitly searches for tags by tags drop-down button. for this, I have created another route "/tags?q=" where all the courses related to this tag will be shown. the tag search page is the almost same as the search page the only difference is the part where the code searches for queries in the name of AllCourseDetail I tweak it a bit to search for tags.
