Remove deprecated ML job property from test fixtures (#207857)\n\n##
Summary\r\n\r\nReplace `estimated_heap_memory_usage_bytes` property with
`expected\r\nmodel_size_bytes` per deprecation warning. I unzipped the
fixture\r\narchives, replaced the property, and rezipped them.\r\n\r\n##
To test\r\n\r\nAdd the following to your `serverArgs` block
in\r\n`x-pack/test/fleet_api_integration/config.base.ts`\r\n\r\n```\r\n{\r\n
name: 'elasticsearch.debug',\r\n level: 'debug',\r\n appenders:
['default'],\r\n},\r\n```\r\n\r\nRun the EPM FTR tests e.g.
\r\n\r\n```\r\nFLEET_PACKAGE_REGISTRY_PORT=12345 yarn test:ftr:server
--config x-pack/test/fleet_api_integration/config.epm.ts \r\n\r\n# in

test:ftr:runner --config x-pack/test/fleet_api_integration/config.epm.ts
--grep \"Assets tagging\"\r\n```\r\n\r\nCheck that the deprecation
notice does not appear in the\r\n`elasticsearch.debug` logs in your
console\r\n\r\n```\r\nx-pack/test/fleet_api_integration/apis/epm/bulk_get_assets.ts:
