fix: node-fetch hanging issue when fetching checksum after fetching binary

[xmliszt]

What kind of change does this PR introduce?

• Bug fix:

Fix node-fetch fetch command hangs indefinitely when fetching the checksum file after fetching the binary, on some macOS devices that have stricter network restrictions. This PR will fix #2798

• Misc:

Added some comments to explain the process clearly.

What is the current behavior?

#2798 : running npm install supabase@latest --save-dev hangs and failed after waiting for a long time, the error happens at the fetching of the checksum file. However, running sudo npm install ... works.

Some investigation shows that this error starts happening from version 1.90.0, version 1.89.1 did not have such issue. The change that was made between these two version is in this commit: 571f336

By examining the commit, it shows that checksum verification was added as a result, and since then the checksum fetch was run after the fetching of the binary.

What is the new behavior?

By fetching the checksum file (small in size) before fetching the binary file (big in size), both fetch succeeded without error.
