dev-master no longer works in main branch (it does in 2.x)

**Describe the bug**
when updating a dependency using "composer update vendor/packagename" and in the composer json the require is like this:

```
"repositories": {
{
"type": "composer",
"url": "https://packagist.vendor.tld"
}
},
"require": {
"vendor/packagename": "dev-master"
}
```
the dependency is not updated

**To Reproduce**
Provide configuration file(s) and the exact command that you invoked.

`php satis/bin/satis build satis.json public/`
the public is hosted on https://packagist.vendor.tld

satis.json
```
{
"name": "vendor/packagist",
"homepage": "https://packagist.vendor.tld",
"repositories": [
{ "type": "vcs", "url": "https://code.vendor.tld/git/packagename.git" }
],
"require-all": true
}
```

**Outcome**
no errors, works as it always did.

**Expected behavior**
The latest version of vendor/packagename is retrieved when using "composer update vendor/packagename"

**Additional context**
This bug happens on the main branch, if we use branch 2.x it works perfect :)

We think it has something todo with the composer 2 dependencies that are updated but other then that we are in the dark...
