Allow sourcemaps upload to exit with non-zero status if an upload fails

[Mahoney]

Feature request description

We recently failed to notice our sourcemap uploads were not happening on CI because while datadog-ci sourcemaps upload prints out this output:

❌ Failed upload sourcemap for [/root/sourcemaps/assets/chunk.0af6818d23009e1ee6d2.js.js.map]: Missing corresponding JS file for sourcemap (/root/sourcemaps/assets/chunk.0af6818d23009e1ee6d2.js.js)

it still exits 0, so we never knew.

Solution

There should be at least a flag to the command to make it exit non-zero if any of the uploads fail.
