v10.x branch npm dep update

[lpusok]

Would like to update npm dep to 6.13.7 (up from 6.13.4) on the LTS v10.x branch.

It was updated in master here: #31558

@BethGriggs what is the process for this?

This will fix a macOS brew specific issue (in a hosted CI enviroment at Bitrise), when npm i -g npm@<other_npm_version> fails with permission issue:

npm ERR! code EEXIST
npm ERR! syscall symlink
npm ERR! path ../../../lib/node_modules/npm/man/man1/npm-access.1
npm ERR! dest /usr/local/share/man/man1/npm-access.1
npm ERR! errno -17
npm ERR! EEXIST: file already exists, symlink '../../../lib/node_modules/npm/man/man1/npm-access.1' -> '/usr/local/share/man/man1/npm-access.1'
npm ERR! File exists: /usr/local/share/man/man1/npm-access.1
