support binary deploy in npm packages (#21589)

backport of #21372 for v1.17.4

-------------------

npm package.json supports binary packaging:
https://docs.npmjs.com/cli/v8/configuring-npm/package-json#bin

the npm registry documents that the binary references will be attached
to the abbreviated version object:

https://github.com/npm/registry/blob/master/docs/responses/package-metadata.md#abbreviated-version-object

unfortunately their api documentation leaves this out:
https://github.com/npm/registry/blob/master/docs/responses/package-metadata.md#abbreviated-version-objectdoc

which is likely to be the reason this was left out in gitea's initial
implementation

this response is critical for npm to install the binary in the .bin
folder so as to be included on the users default bin path, resulting in
immediate access to any binaries provided by the package

i have tested upload and installing through npm and can confirm the npm
registry now responds with bin in the version metadata and results in
the binary being available after install.

this fixes https://github.com/go-gitea/gitea/issues/21303
