fix(docs): add -p parameter to the cargo run commands in documentation

[dj707chen]

Add -p parameter to the cargo run commands in README.md files and other documentation to fix error.

Motivation and Context

When I launched the following command as documented in examples/servers/README.md at the examples/server directory:

cargo run --example servers_counter_stdio

It ran well, but when I launched it at repository root or places other than the examples/server subtree, I got error:

error: no example target named `servers_counter_stdio` in default-run packages

Add the -p parameter to make it runs at all places:

cargo run -p mcp-server-examples --example servers_counter_stdio

How Has This Been Tested?

Run the new commands at repository root or places other than the examples subtree, the server should be launched without errors.

@dj707chen Can you update the commit messages to follow https://www.conventionalcommits.org/en/v1.0.0/ format? Then we can get this in

[dj707chen]

Oh, didn't know the convention, that's neat! Prefixed the 3 commit messages with "fix(docs): ", not sure if I did it in a correct way.

@dj707chen All that needs to change now is the first letter of the subject cannot be uppercased. Sorry for the hassle. I am going to merge the PR anyway and I'll look at disabling some of the unnecessary strictness tomorrow.

I did #619 earlier today which will also verify messages on pre-commit as a useful shift-left.
