Issue:
Bug: router crate fails to build in WSL unless more memory is added



I am part of a student team hoping to contribute to hyperswitch over the next several months. After following the instructions in `docs/try_local_system.md` for setting up a development environment using WSL, all members of my team encountered the same issue: upon running `cargo build`, the `router` crate failed to build, producing an error ending in `signal: 9, SIGKILL: kill`.

After some research, we came across [this discussion post](https://github.com/juspay/hyperswitch/discussions/758), where the author encountered a similar issue. After trying the suggested solution of configuring WSL to allow an additional 2GB of memory, the issue persisted, however we were able to resolve it by increasing the amount to 24GB.

Some of our machines do not have 24GB of memory, so we ended up editing `.wslconfig` to include 8GB of memory, and then adding an additional 16GB via a swap file created from within the WSL terminal.

Because the same issue occurred for all of us in the exact same way, across different machines, we feel that `docs/try_local_system.md` should mention the issue, along with instructions on how to configure WSL to prevent the issue from occurring.
