##### Summary
Document " <, >, <=, => " operators in name parameter of yum/dnf module. Currently the documentation does not mention that comparison operators are available, but they do work.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
yum/dnf module

##### ADDITIONAL INFORMATION
The value operators work currently in the yum/dnf modules
```
yum :
   name: "pkg >= 1"
   state: present
```

Yum/dnf will determine the version available and install it if it matches the comparison operator

- If a previous version is specified, the task also needs to turn C(allow_downgrade) on.
        See the C(allow_downgrade) documentation for caveats with downgrading packages.
      - When using state=latest, this can be C('*') which means run C(yum -y update).
      - You can also pass a url or a local path to a rpm file (using state=present).
        To operate on several packages this can accept a comma separated string of packages or (as of 2.0) a list of packages.
    aliases: [ pkg ]
    type: list
    elements: str
  exclude:

      - Package name(s) to exclude when state=present, or latest
    type: list

    description:
      - "Package name to run the equivalent of yum list --show-duplicates <package> against. In addition to listing packages,
        use can also list the following: C(installed), C(updates), C(available) and C(repos)."
      - This parameter is mutually exclusive with C(name).
    type: str
  state:
    description:
      - Whether to install (C(present) or C(installed), C(latest)), or remove (C(absent) or C(removed)) a package.
      - C(present) and C(installed) will simply ensure that a desired package is installed.
      - C(latest) will update the specified package if it's not of the latest available version.
      - C(absent) and C(removed) will remove the specified package.
      - Default is C(None), however in effect the default action is C(present) unless the C(autoremove) option is
        enabled for this module, then C(absent) is inferred.
    type: str
    choices: [ absent, installed, latest, present, removed ]
