Update protocol to submodules

[QuellaZhang]

Submodules will no longer download as the git: protocol, reference https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git, update the protocol to https://. Fixed #20714.

Can someone help approve the PR? Thanks!

I just pulled down fresh git clone to test out v4 again and ran into this issue.
Ideally someone who can merge this will also update the v3 branch with the same replace git:// with https://.

I just tried v4 on an M1 machine (I finally own one) and I ran into this issue. Let's get it in front of engineering to have the fix merged for v4 and v3 branches.

I have this in .gitmodules

[submodule "tools/cocos2d-console"]
        path = tools/cocos2d-console
        url = https://github.com/cocos2d/cocos2d-console.git
[submodule "tools/bindings-generator"]
        path = tools/bindings-generator
        url = https://github.com/cocos2d/bindings-generator.git
[submodule "tests/cpp-tests/Resources/ccs-res"]
        path = tests/cpp-tests/Resources/ccs-res
        url = https://github.com/dumganhar/ccs-res.git

but I still seem to be doing the same error:

did I make a mistake? I also read the blog post.

[stevetranby]

Not sure why it's not using the https version, but your git submodule command looks like it tried to clone from the git:// protocol version:

fatal: clone of 'git://github.com/dumganhar/ccs-res.git'

You need to figure out how to get the git submodule command to use the updated .gitmodules? Not sure how? Maybe you have something cached? Maybe you updated the wrong .gitmodules? Maybe you need to restart (for the proverbial fixes everything potential?)

I also ran into the same issue and fixing the .gitmodules file was not sufficient. I also had to edit .git/config file and replace git refferences with https url.
I recommend adding a note on the README or approving the PR asap to avoid recurring errrors

Until the fix is merged, I resolved problem by running the following command (which makes git run https protocol instead of git for github.com:

git config --global url.https://github.com/.insteadOf git://github.com/

Please check this. Yes, the git protocol can't work now. The error log is:

Cloning into 'F:/cocos2d-x/tests/cpp-tests/Resources/ccs-res'...
fatal: unable to connect to github.com:

The issue this PR will solve is still ongoing, it needs to be merged ASAP.
