README.md step 3 discusses building MediaInfo when build-s3-dist.sh already handles this later on.

Describe the bug
README.md discusses in step 3 of the manual build process a task to compile MediaInfo or download it into the source distribution. The latter is handled automatically as part of the build-s3-dist.sh script that is run later.

To Reproduce
Run build-s3-dist.sh and you will see it download mediainfo into the right location. This seems to be hard coded to a specific release which is a few versions out of date now.

Expected behavior
Update the docs to not include this task as it consumes time unnecessarily.
Stretch to update the download script to get the latest version of MediaInfo rather than fixed release.

Please complete the following information about the solution:

• Version: [e.g. v1.0.0]

To get the version of the solution, you can look at the description of the created CloudFormation stack. For example, "(SO0021) - Video On Demand workflow with AWS Step Functions, MediaConvert, MediaPackage, S3, CloudFront and DynamoDB. Version v5.0.0". If the description does not contain the version information, you can look at the mappings section of the template:

Mappings:
  SourceCode:
    General:
      S3Bucket: "solutions"
      KeyPrefix: "video-on-demand-on-aws/v5.0.0"

• Region: [e.g. us-east-1]
• Was the solution modified from the version published on this repository?
• If the answer to the previous question was yes, are the changes available on GitHub?
• Have you checked your service quotas for the sevices this solution uses?
• Were there any errors in the CloudWatch Logs?
