Update jsonwebtoken

[Gnito]

SDK does not work with Node v24.0.0 nor v25.0.0

It fails with error:

/[..]/web-template/node_modules/buffer-equal-constant-time/index.js:37
var origSlowBufEqual = SlowBuffer.prototype.equal;
                                  ^
TypeError: Cannot read properties of undefined (reading 'prototype')

buffer-equal-constant-time is a nested dep: jsonwebtoken > jws > jwa > buffer-equal-constant-time

auth0/node-jsonwebtoken#992
(There's also web-template issue created: 794)

The issue is fixed on jsonwebtoken: v9.0.3
(auth0/node-jsonwebtoken#1007)
