Mock file path not altered

First off @nealrichardson, thanks so much for this awesome package! I've just started switching all my pkgs over to httr2 + httptest2, and this package make mock testing so easy. Awesome work!

Now to business: The following reprex demonstrates that, although gsub_response() should also modify the request via #8, the file path in httr::req_body_file() is not modified:

f <- tempfile ("data-", fileext = ".dat")
saveRDS (datasets::Orange, f)
u <- "https://my.upload.site"
req <- httr2::request (u) |>
    httr2::req_method ("PUT") |>
    httr2::req_headers ("Content-Type" = "application/octet-stream") |>
    httr2::req_body_file (path = f)

req$body$data
#> [1] "/tmp/RtmpW0CH4X/data-417e1b18af5c.dat"
#> attr(,"class")
#> [1] "httr2_path"

httptest2::gsub_response (
    req$body,
    paste0 ("[A-Za-z0-9]*", .Platform$file.sep, "data\\-"),
    paste0 ("tempdir", .Platform$file.sep, "data-"))
#> $data
#> [1] "/tmp/RtmpW0CH4X/data-417e1b18af5c.dat"
#> attr(,"class")
#> [1] "httr2_path"
#> 
#> $type
#> [1] "raw-file"
#> 
#> $content_type
#> [1] ""
#> 
#> $params
#> list()
#> 
#> $url
#> character(0)

The files output by httptest2 then have a part of the tempdir hash in their names, and so are not able to be reproduced, leading to test failures. In other words, a function issuing the req given above fails mock tests because the paths differ each time the test is run. I'd really appreciate any help you could offer. Thanks!
