Support auto upgrade docs for manually maintained connector.

[shibd]

For examples:

This script will use aws-eventbridge connector as the target version.

If Specimen(aws-eventbridge) versions: [ 'v2.10.5.8', 'v2.11.2.12', 'v3.0.1.6', 'v3.1.0.5' ]
And if a connector for manually maintained versions: [ 'v2.10.5.5', 'v2.11.2.10' ]

Then, it will be automatically upgraded through the following rules, and the download link will be updated automatically.

[
{ from: 'v2.10.5.5', to: 'v2.10.5.8' },
{ from: 'v2.11.2.10', to: 'v2.11.2.12' },
{ from: 'v2.11.2.10', to: 'v3.0.1.6' },
{ from: 'v2.11.2.10', to: 'v3.1.0.5' }
]

Note

• If a connector dir has xxx.yaml, that means that it is a connector that automatically syncs documents.
• Otherwise, the connector documentation is manually maintained, and the documentation version will be automatically updated when we have a new streamnative release.
• All connector docs versions role: vx.x.x.x.
