Upgrade gatling version to 3.9.5

[gold-kou]

Description

• Upgrade gatling version to 3.9.5
• Upgrade java version to 17
• Add rm option to use gatling.sh

I checked this change works correctly at my local by following commands.

$ make kind-create
$ kubectl config use-context kind-gatling-cluster 
$ make build 
$ make install-crd 
$ make kind-deploy 
$ make kind-sample-deploy

Also, I confirmed that Gatling 3.2.1 works fine with rm option. This means whether upgrading gatling version or not is up to gatling-operator users.

I think it's ok to leave the comment in this section.

I believe it's a good practice to include the Debian version name for clarity.
It can be confusing otherwise, whether it's buster, bullseye, or bookworm.
Since this image is based on bullseye, I'd suggest tagging it as 17-jdk-slim-bullseye.

• It's should standardize on 'apt-get'.
• I recommend adding apt-get upgrade -y to apply package updates.
• bash is unnecessary because it's installed by default.

Suggested change

	RUN apt-get update && apt install -y wget bash libc6-dev unzip && \
	RUN apt-get update && apt-get upgrade -y && apt-get install -y wget libc6-dev unzip && \

I think libc6 is required in Alpine, but I don't think it's necessary in Debian.
