Add Summary Section to the template

Currently, the resume template does not include a section for the profile summary, which I believe is equally important.

For reference, here are the PRs which added summary functionality but were reverted at some point to focus on Resumake v3:

• https://github.com/saadq/resumake.io/pull/108
• https://github.com/saadq/resumake.io/pull/106
• https://github.com/saadq/resumake.io/pull/126
