Add --no-install-recommends option in args of apt-get

[kota2and3kan]

Description

This PR adds the --no-install-recommends option in arguments of the apt-get command in the Dockerfile.

It seems that, now, using the --no-install-recommends option is recommended in the Building best practices of Docker. It can avoid installing unnecessary packages when we run the apt-get command.

• FYI:
  • Manual page of the apt-get command. You can see the details of the --no-install-recommends option.
    • https://manpages.ubuntu.com/manpages/noble/en/man8/apt-get.8.html
  • The PR that the --no-install-recommends option is added in Docker documentation.
    • Update best-practices.md docker/docs#21045

Please take a look!

ledger/Dockerfile:13

• [nitpick] The --no-install-recommends option has no effect when used with apt-get upgrade (it only applies to install). Consider whether this option is necessary here or if it should instead be applied to any apt-get install commands.

RUN apt-get update && apt-get upgrade -y --no-install-recommends \

client/Dockerfile:3

• [nitpick] The --no-install-recommends option has no effect when used with apt-get upgrade. Verify whether this flag is needed here or if it should be applied to apt-get install operations instead.

RUN apt-get update && apt-get upgrade -y --no-install-recommends \
