--file-list ignored

**Describe the bug**
When using `sign code azure-key-vault`:
- we have to provide a list of files, even when a `--file-list` parameter is provided
- when we provide a list of files, the `--file-list` parameter seems to be simply ignored
- the example in the docs folder specify both a '*' as the list of files an a `--file-list`
- there is no documentation about the relationship between these two parameters

**Repro steps**

sign-list.txt:
```
myapp.exe
my.*.dll
```

dir:
```
myapp.exe
my.first.dll
my.second.dll
other.dll
```

Only file-list not accepted:
```pwsh
sign code azure-key-vault `
> -fl "D:\code\project1\sign-list.txt" `
> --base-directory "D:\code\project1\bin\Release\net10\" `
> --azure-key-vault-tenant-id "xxx" `
> --azure-key-vault-client-id "yyy" `
> --azure-key-vault-client-secret "zzz" `
> --azure-key-vault-url "https://xxx.vault.azure.net/" `
> --azure-key-vault-certificate "foo" `
> -d "My App" `
> -v Information `

Required argument missing for command: 'azure-key-vault'.
```

wildcard results in all files signed (file-list ignored):
```pwsh
sign code azure-key-vault `
> -fl "D:\code\project1\sign-list.txt" `
> --base-directory "D:\code\project1\bin\Release\net10\" `
> --azure-key-vault-tenant-id "xxx" `
> --azure-key-vault-client-id "yyy" `
> --azure-key-vault-client-secret "zzz" `
> --azure-key-vault-url "https://xxx.vault.azure.net/" `
> --azure-key-vault-certificate "foo" `
> -d "My App" `
> -v Information `
> *

Submitting D:\code\project1\bin\Release\net10\myapp.exe for signing.
Submitting D:\code\project1\bin\Release\net10\my.first.dll for signing.
Submitting D:\code\project1\bin\Release\net10\my.second.dll for signing.
Submitting D:\code\project1\bin\Release\net10\other.dll for signing.
```

single file results in only this file signed (file-list ignored):
```pwsh
sign code azure-key-vault `
> -fl "D:\code\project1\sign-list.txt" `
> --base-directory "D:\code\project1\bin\Release\net10\" `
> --azure-key-vault-tenant-id "xxx" `
> --azure-key-vault-client-id "yyy" `
> --azure-key-vault-client-secret "zzz" `
> --azure-key-vault-url "https://xxx.vault.azure.net/" `
> --azure-key-vault-certificate "foo" `
> -d "My App" `
> -v Information `
> myapp.exe

Submitting D:\code\project1\bin\Release\net10\myapp.exe for signing.
```

**Expected behavior**
There should be a clear relationship between files and --file-list:
- should be combined
- no files should be allowed when file-list is set
- documented

**Actual behavior**
--file-list seems to be ignored
