fix(section-1): corrects relative path in src/demos/section-1/001_providing-a-service-01.ts

[olange]

Minor change to allow running the first demo of section 1.

What?

src/demos/section-1/001_providing-a-service-01.ts raises a CacheMissError when trying to run it.

Why?

The lookup() method in FileSystemCache was attempting to read from src/demos/session-1/cache/${key}.
But the correct path is src/demos/section-1/cache/${key}.

Before

try: () => fs.readFile(`src/demos/session-1/cache/${key}`, "utf-8"),

After

try: () => fs.readFile(`src/demos/section-1/cache/${key}`, "utf-8"),

Testing

With this fix, the expected output is:

% pnpm exercise src/demos/section-1/001_providing-a-service-01.ts

in-memory-value1
file-value2

Previously, the output was:

[…]
in-memory-value1
CacheMissError: Failed to read file for cache key: "key2"
