PR template addition

[0xc0170]

We would like to show users how a good pull request look like. I used code highlight for the template, is that fine or better solutions ?

The main points that should be coevred:

• describe your changes (what is being changed and how)
• how it was tested (targets, toolchains, etc)
• pull request type (can be one of, not a mixture!)

The template is being updated here ARMmbed/mbed-os#6078

One small nit, but not blocking. LGTM!

I would recommend we be specific here, to encourage others to be specific as well.

Replace "two targets" with something like "K64F and K66F".

[cmonr]

Like the checklist.

@adbridge @theotherjimmy @kjbracey-arm Please review

Agree with Cruz about being specific as to which two targets were tested against. But otherwise looks like a nice simple example. Can always be refined down line, good to get something in.

I had it first (named two targets I randomly chose) , but did not want to pick up only two targets (which ones we would select), lets see how this goes with users (what info are we going to get) and can add some info about being more specific

Is it OK to merge this before 6078 merges?

@AnotherButler Yup! It even seems like that PR is waiting on this! ARMmbed/mbed-os#6078 (comment)
