Building backend throws "Subsequent property declarations must have the same type" error

[trivikr]

Describe the bug

The command yarn build:backend throws "Subsequent property declarations must have the same type" error

Steps to reproduce

Run yarn build:backend

Observed behavior

Following error is thrown:

../../node_modules/@types/react/index.d.ts:3317:13 - error TS2717: Subsequent property declarations must have the same type.  Property 'tspan' must be of type 'SVGProps<SVGTSpanElement>', but here has type 'SVGProps<SVGTSpanElement>'.

3317             tspan: React.SVGProps<SVGTSpanElement>;
                 ~~~~~

  ../../node_modules/@types/reach__router/node_modules/@types/react/index.d.ts:3167:13
    3167             tspan: React.SVGProps<SVGTSpanElement>;
                     ~~~~~
    'tspan' was also declared here.

Expected behavior

Build for backend successful.

This appears to be an issue with reach router.
It would be fixed on moving to React Router 6 in #60

The error is no longer thrown on running yarn build:backend

The lock file maintenance PR in #76 would have fixed it.
