Search Optimization

[Abh1noob]

resolves #112

• Created new component <SearchBar/> and renamed older compoent to <SearchBarChild/>.
• Made <SearchBar/> a server component where I call /api/course-list endpoint , and pass the response into client component <SearchBar/> through props.
• The data is saved in state and searching takes place consuming that state
• Waiting for response after every keystroke led consumed more time for searching and its fast now this way
