Summary

📄🐛🆕

This pull request modifies the frontend code of several providers to export a single YAML file instead of a ZIP file when exporting templates or applications. This simplifies the export process and removes the dependency on JSZip. It also adds support for the new template type attribute in the backend and fixes a bug in the cronjob provider.

We're sailing on the code sea, me hearties
We're exporting YAML files with ease
We've fixed some bugs and added some features
We're pulling and pushing on the count of three

Walkthrough

• Simplified the export process of YAML files by removing the dependency on JSZip and exporting a single YAML file instead of a ZIP file containing multiple YAML files (link, link, link)
• Fixed a bug in the getUserServiceAccount function in the user.ts file by returning the user field from the context object instead of the namespace field (link)
• Added the template_type field to the TemplateType type definition in the app.ts file and the handleTemplateToInstanceYaml function in the json-yaml.ts file to support the new template type attribute that was introduced in the backend (link, link, link)
• Improved the user experience by providing sensible defaults for the template inputs using the defaultInputes variable and the generateCorrectYaml function in the index.tsx file (link)
• Moved the > character to the previous line in several files to follow the code style convention of the project (link, link, link, link, link, link, link, link, link, link, link, link, link, link, link, link)
