Add BIOS options with alternate wording

[KallynGowdy]

Currently, the available BIOS options are:

• static inst - Loads an inst as a device-only experience.
• private inst - Loads an inst from a record.
• public inst - Loads a temporary inst that is publicly available.
• sign in - Prompts the user to sign in.
• sign up - Prompts the user to sign up.
• enter join code - Prompts the user to enter a join code to join a shared inst.

This task is to add the following options:

• local inst - Works exactly like static inst.
• studio inst - Works exactly like private inst.
• free inst - Works exactly like public inst.

Each option should have an additional description so that the function of the option is more clear to the user.

Additionally, the list of default BIOS options should change to:

• enter join code
• localinst
• studio inst
• free inst
• sign in
• sign up

Finally, the following options should be supported for the ?bios= query parameter:

• local inst - Works exactly like static inst.
• studio inst - Works exactly like private inst.
• free inst - Works exactly like public inst.
• local - Works exactly like local inst and static inst.
• studio - Works exactly like studio inst and private inst.
• free - Works exactly like free inst and public inst.
