Update Pt2 title-screen to hardware.inc v5.3.0

[hlatourette]

Same as #140 (addressing #125) to keep Part II hardware.inc version consistency across sections of a given part of the tutorial. Title screen was merged prior to PR 140 (in #137) and wasn't covered in that change set.

Looks like this may also need to be done to the serial-link section that was introduced and merged in #88. Can do that here as well if you want.

Confirmed build using Dockerfile:

FROM ghcr.io/gbdev/rgbds:latest AS build
RUN apt-get update && apt-get install -y && \
    apt-get autoremove && \
    apt-get -y clean && \
    rm -rf /var/lib/apt/lists/*
COPY . /usr/local/src/unbricked
WORKDIR /usr/local/src/unbricked
RUN ./build_all.sh

Output

docker build --target=build -t unbricked .

Thanks @hlatourette !

No prob @avivace, I'll go ahead and open on to update the Serial Link section of Pt II as well. Though I did notice the markdown page has some potentially odd rendering going on?
