It's a typo. They probably mean 0.1uF.

I've never seen anything that ever used 0.1F. There might possibly be some industrial application where such a value is used, but in audio electronics? No way. Even the big power smoothing caps in a power supply rarely get as high as 10,000uF, let alone 100,000uF.

Pin 5 is used as Control Voltage pin, which controls the timing of the 555 by overriding the 2/3Vcc level of the voltage divider network..
(by applying a voltage to this pin the width of the output signal can be varied independently of the RC timing network..)

When not used, like in your case, it's connected to ground via a 10nF - 100nF capacitor to eliminate any noise..

P.S.

The issue is that I cannot find one such capacitor is any electronics store around.

You can always wire in parallel 100,000 x 1nF or 10,000 x 10nF or 1,000 X 100nF..
(or better, use your imagination for say,  (200 x 470nF) // (6 x 10nF) or anything else you consider warped enough..)

Thank you both for clarifications! I was doubly confused because I've never actually seen a capacitor above 1000uF and also because time calculation formula is for the schematic is in farads.

Sometimes I forget that parallel wiring is a thing but this time I'm kind of glad I did.
