Need to update some pin names in tt.dump()

[urish]

Instead ofnprojectrst, it should say rst_n and instead of rp_projclk, it should say clk (to match the TT pin names)

>>> tt.dump()

Demoboard status
Demoboard default mode is ASIC_RP_CONTROL
Project nRESET pin is IN 1
Project clock PWM enabled and running at 10000000
Selected design: tt_um_urish_spell (642) @ https://github.com/urish/tt06-spell
