StringLiteralExprSyntax adds whitespace in front of closingQuote

### Description

I'm using version `600.0.1` and wrote this code as part of a macro expression:

```swift
let defaultValueLiteral = StringLiteralExprSyntax(
openingQuote: .stringQuoteToken(),
segments: StringLiteralSegmentListSyntax([.stringSegment(.init(content: "Some Text"))]),
closingQuote: .stringQuoteToken()
)
```

When I return it in my `ExpressionMacro` wrapped into an `ExprSyntax`, the expanded code looks like this:

```swift
"Some Text "
```

But I expect it to be:

```swift
"Some Text"
```

Am I missing something?

### Steps to Reproduce

Here's a more complete code example:

```swift
public struct TranslationKey: ExpressionMacro {
public static func expansion(
of node: some FreestandingMacroExpansionSyntax,
in context: some MacroExpansionContext
) throws -> ExprSyntax {
// constructing: `"Some Text"`
let defaultValueLiteral = StringLiteralExprSyntax(
openingQuote: .stringQuoteToken(),
segments: StringLiteralSegmentListSyntax([.stringSegment(.init(content: "Some Text"))]),
closingQuote: .stringQuoteToken()
)

// I have actually more code here (just in case you were wondering)

return ExprSyntax(defaultValueLiteral)
}
}
```
