chore(cmd/info): Fix printed spacing of summary. (hypermodeinc#1559)

* chore(cmd/info): Fix printed spacing of summary.

Column-aligns the output for the Summary section:

Before:

    [Summary]
    Level 0 size:          0 B
    Level 1 size:       2.3 kB
    Total SST size:   2.3 kB
    Value log size:       20 B

After:

    [Summary]
    Level 0 size:          0 B
    Level 1 size:       2.3 kB
    Total SST size:     2.3 kB
    Value log size:       20 B

* fix: Set block cache and index cache sizes.

This fixes a panic when running badger info

    panic: BlockCacheSize should be set since compression/encryption are enabled
