feat: implemented page for sprint 2 and 3

[yaslam-dev]

Changes

1. Using Webpack instead of tsc to transpile code.
2. Using Nodemon for HMR.
3. A few files weren't ignored by the vscode package; it's fixed now.
4. Previously we were using global state of vs code to communicate information between webview and extension; Now this is replaced with lightweight event emitter implementation; which can send messages directly to webview thus improving the user experience and reliability of the code.

Missing from this PR that will be addressed in the upcoming PR.

1. Testcases
2. By Default extension should inherit the vs-code theme.
3. Back button on Recommendation Page.
4. Other files with problems features

Implementation

1. Sprint 2 and Sprint 3 screens implemented.

Some notes, these can be addressed in pr #30:

• There is a 1-2 second delay between clicking 'more details' and the left panel updating
• Discarding a problem using the 'Discard' button should remove the problem from the left panel (It already removes the highlight) The inconsistency will lead to confusion

Other than those, it looks good. I'll merge it shortly
