fix(debos): Bump imagesize to 4.5GiB

Effective rootfs size in current images is about 3.4G and is 99% full;
latest builds fail due to lack of space. Bump the default imagesize in
image.yaml and README to 4.5GiB, which is roughly 512MiB for ESP and
4GiB for rootfs. The debos imagesize parsing is based on docker/go-units
which was confirmed to support fractional sizes correctly.

 For the image recipe:
 - `dtb`: override the firmware provided device tree with one from the linux kernel, e.g. `qcom/qcs6490-rb3gen2.dtb`; default: don't override
 - `imagetype`: either `ufs` (the default) or (`sdcard`); UFS images are named disk-ufs.img and use 4096 bytes sectors and SD card images are named disk-sdcard.img and use 512 bytes sectors
-- `imagesize`: set the output disk image size; default: `4GiB`
+- `imagesize`: set the output disk image size; default: `4.5GiB`
 
 For the flash recipe:
 - `u_boot_rb1`: prebuilt U-Boot binary for RB1 in Android boot image format -- see below (NB: debos expects relative pathnames)
