How to reproduce:
1. Create a new HDRP project
2. Go to Window -> Rendering -> Lighting
3. Click "Generate Lighting"
4. Observe the Background Task

Expected results: The calculated time is close to the time the task takes and the progress bar moves gradually along the processes
Actual results: The progress bar jumps to an end and displays 2-5 seconds for around 4-5 minutes

Reproducible with: 2023.2.0a1, 6000.0.24f1
Not reproducible with: 2021.3.45f1, 2022.3.50f1, 2023.1.0b1

Reproducible on: macOS Sequoia 15.0 (M1 Max)
Not reproducible on: No other environment tested

Notes:

• The progress bar displays the process like it's almost finished
• When jumping to that stage, the calculated time starts at 2 seconds and grows on one second each minute (usually goes up to 5 seconds)
• This state of progress bar and remaining time is redundant because it is not close to the real time
• Best to be observed in bigger projects (HDRP or URP sample)
• In 6000.0.24f1 the bug happens on the third stage of light baking, in 2023.2.0a1 - on the first
• There are slight differences in the behavior between newer and older versions but overall it remains the same
