CI: Update actions to run on Node16 instead of Node12

We are encountering warnings such as:

The following actions uses node12 which is deprecated and
will be forced to run on node16: actions/checkout@v2,
actions/setup-go@v2.

More information about this warning can be found at:
https://github.blog/changelog/2023-06-13-github-actions-all-
actions-will-run-on-node16-instead-of-node12-by-default/

Changing checkout to actions/checkout@v3 or above and setup-go
to setup-go@v3 or above resolves the issue as v3 version on
both uses node16 runtime by default.
Refer:
https://github.com/actions/checkout/releases/tag/v3.0.0
https://github.com/actions/setup-go/releases/tag/v3.0.0

Hence updated checkout to v3 and setup-go to v4(to get
benifited from latest cache related change as well along
with the node 16 support:
