Feat/rust tools

[YOU54F]

relates to pact-foundation/pact-ruby-standalone#146

add rust tools to package

Couple of ways we can do it

1. update entrypoint.sh to allow rust commands and delegate directly to them
2. update cli.rb to allow entries in the main cli docs that run without a command. This means we can mark the ruby equiv tools as legacy, and prefer the use of the rust tools.
3. do both :) everyone loves options

we can also do both, which will allow a user to enter the rust command

   version                         # Print the version of the CLI

Notes

• ⚠️ drops ARM support (no supported flavours of rust)
  • We could conditionally ignore, but it will speed up runs, as arm is under emulation.

TODO

• docs of usage
• website docs
• update breaking change notation in commit entries
