function Deno.makeTempFileSync
makeTempFileSync(options?: MakeTempOptions): string
Synchronously creates a new temporary file in the default directory for
temporary files, unless `dir` is specified.
Other options include prefixing and suffixing the directory name with
`prefix` and `suffix` respectively.
The full path to the newly created file is returned.
Multiple programs calling this function simultaneously will create
different files. It is the caller's responsibility to remove the file when
no longer needed.
```ts
const tempFileName0 = Deno.makeTempFileSync(); // e.g. /tmp/419e0bf2
const tempFileName1 = Deno.makeTempFileSync({ prefix: 'my_temp' }); // e.g. /tmp/my_temp754d3098
```
Requires `allow-write` permission.
