Issue Resolved / Feature Added

After #3166, 'npm run bootstrap' does not link internal packages automatically.

Resolution

As we use npm higher than 7 now, we can use npm workspaces.

• Updated our monorepo to use npm workspaces
• Removed Lerna as we do not use any complex function of Lerna
• Made 'npm install' to make an internal link also
• Made 'npm run clean' to remove 'node_modules' of the root path also
• Removed 'npm run publish' as we don't use it anymore
• But, kept the existing run scripts rather than removing them for any scripts
• Updated a related document
