Announce this publicly once it is ready for wider usage

Once we fix the following issues:

• CI (Run the CI for all pull requests, ensuring the page can build #15)
• Runtime library (LFortran Runtime Library not available #10)

And generally fix the most basic bugs (let's update the above list with everything that needs fixing), we should:

• Add a link to lfortran.org
• Add a link to fortran-lang (Link to LFortran WASM compiler fortran-lang/webpage#46)
• Write a blog post

• It seems we have a basic CI which builds the site and uploads it to https://github.com/lfortran/pull_request_preview. (It currently overrides the previous deployment as shared here Run the CI for all pull requests, ensuring the page can build #15 (comment)). This preliminary CI could help ensure if the page can build and if the site works.
• We also have basic support for the runtime library at https://dev.lfortran.org/ (Functions like kind(), abs(), floor(), etc. currently work at https://dev.lfortran.org/)

Yes, for the runtime library the remaining issue to fix are the parts implemented in C. However, the current version is already very usable, so we should announce it and add it to lfortran.org.
