fix: stray | pipe in docker create --help

[hirehamir]

- What I did

I removed a stray | from the --pull flag description on docker create. It made

docker create --help

list the accepted values as ("always", "|missing", "never").

- How to verify it

Before:

--pull string                      Pull image before creating ("always", "|missing", "never") (default "missing")

After:

--pull string                      Pull image before creating ("always", "missing", "never") (default "missing")

- Human readable description for the release notes

Fixed a typo in the docker create --pull flag description
