Reproduction with the VSCode reference client

• I have confirmed this issue also reproduces with the VSCode reference client.
• This issue does NOT reproduce with the VSCode reference client, but I believe JETLS-side changes are needed.

Description

When using a VSCode workspace, .JETLSConfig.toml is ignored

Example:
A file MyWorkspace.code-workspace

{
	"folders": [
		{
			"path": "."
		},
		{
			"path": "../SymbolicAWEModels"
		},
		{
			"path": "../VortexStepMethod"
		},
		{
			"path": "../KiteUtils"
		}
	],
	"settings": {}
}

In each of the folders I have a file .JETLSConfig.toml with the content:

formatter = "JuliaFormatter"

[full_analysis]
auto_instantiate = false            # boolean, default: true

[diagnostic]
all_files = false                   # boolean, default: true

[[diagnostic.patterns]]
pattern = "not concretized"
match_by = "message"
match_type = "regex"
severity = "off"

[inlay_hint.types]
enabled = false  # Hide type hints; keep `end`-tag hints

All of them are ignored.

If I open only one of the folders of the workspace it works.

Steps to reproduce

1. check out two repos from git
2. create a workspace that contains both
3. open the workspace
4. you will see that the .JETLSConfig.toml files are ignored
