Use keyless authentication for the release

[reakaleek]

Use elastic/oblt-actions/aws/[email protected] for authenticating keyless with OIDC to the AWS account.

I need to do some additional testing.

I'm not fully confident that it will work because of

apm-aws-lambda/.goreleaser.yaml

Lines 89 to 90 in d17142a

	- AWS_ACCESS_KEY_ID={{ .Env.AWS_ACCESS_KEY_ID }}
	- AWS_SECRET_ACCESS_KEY={{ .Env.AWS_SECRET_ACCESS_KEY }}

Need to check if I also need to pass AWS_SESSION_TOKEN and/or AWS_SECURITY_TOKEN

Added AWS_SESSION_TOKEN in d98c84e

because I saw that the aws/auth action adds the AWS_SESSION_TOKEN as an environment variable.
