Error building the binaries after adding reqwest

[Angelmmiguel]

The GitHub Action automation is failing to build the binary due to missing dependencies. After adding reqwest on #74, the project now requires an OpenSSL installation. This is required by the openssl-sys crate, required by reqwest.

Here you can see the error: https://github.com/vmware-labs/wasm-workers-server/actions/runs/4014946928/jobs/6896087632

run pkg_config fail: "pkg-config has not been configured to support cross-compilation.\n\nInstall a sysroot for the target platform and configure it via\nPKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_PATH, or install a\ncross-compiling wrapper for pkg-config and set it via\nPKG_CONFIG environment variable."

  --- stderr
  thread 'main' panicked at '

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

In their documentation, they provide certain commands to install the required dependencies. I will reuse this information and test the build process works properly.
