This is a blocking extension on startup for every project

[robole]

Clearly describe the bug

The extension is loaded on startup for every project. This is due to the activationEvents set to * in the package.json. Extensions with this activation event effectively delay VS Code from becoming active.

The VS Code docs gives the following advice on *:

To ensure a great end user experience, please use this activation event in your extension only when no other activation events combination works in your use-case.

Since, there are other activation event combination open, I would consider this a bug. As a comparsion, ESLint uses onStartUpFinished.

What code is needed to reproduce this issue?

Open any project. You can see stylelint is loaded by running the command Developer: Show Running Extensions.

What vscode-stylelint configuration is needed to reproduce the bug?

No config required.

Is this issue related to autofix? (editor.codeActionsOnSave)

No

Which version of vscode-stylelint are you using?

0.86.0

Which version of stylelint are you using?

Latest version.

Does your issue relate to non-standard syntax (e.g. SCSS, nesting, etc.)?

It is a global issue, it is not tied to a specific syntax.

What did you expect to happen?

I would expect stylelint to be loaded only when a file with CSS-like syntax is open.

What actually happened (e.g. what warnings or errors you are getting)?

The extension is always loaded.

While I realise that stylelint targets many different file types and it is hard to target all of these with onLanguage activation events. Maybe, this would be adequate:

"activationEvents": [
    "onLanguage:css",
    "onLanguage:html",
    "onLanguage:javascript",
    "onLanguage:javascriptreact",
    "onLanguage:less",
    "onLanguage:markdown",
    "onLanguage:postcss",
    "onLanguage:sass",
    "onLanguage:scss",
    "onLanguage:source.css.styled",
    "onLanguage:source.markdown.math",
    "onLanguage:styled-css",
    "onLanguage:sugarss",
    "onLanguage:svelte",
    "onLanguage:typescript",
    "onLanguage:typescriptreact",
    "onLanguage:vue",
    "onLanguage:vue-html",
    "onLanguage:vue-postcss",
    "onLanguage:xml",
    "onLanguage:xsl"
  ],

I suggest at the very least, you can change the activation event to onStartUpFinished to ensure it does not delay startup of VS Code.
