✨ Add support for multiple databases

[viteinfinite]

Description

This PR adds support for querying multiple databases by adding a new nodeTypeName property.

In order to query multiple databases, you can add multiple gatsby-source-notion-api in your project’s gatsby-config.js and set different nodeTypeName values. For instance:

  plugins: [
    {
      resolve: `gatsby-source-notion-api`,
      options: {
        token: `$INTEGRATION_TOKEN`,
        databaseId: `$DATABASE_ID`,
        nodeTypeName: "notionTeamMember",
        propsToFrontmatter: true,
        lowerTitleLevel: true,
      },
    },
    {
      resolve: `gatsby-source-notion-api`,
      options: {
        token: `$INTEGRATION_TOKEN`,
        databaseId: `$DATABASE_ID`,
        nodeTypeName: "notionTask",
        propsToFrontmatter: true,
        lowerTitleLevel: true,
      },
    },
  ],

nodeTypeName is optional and defaults to "Notion", so the change is non-breaking.
